00:30:30.02 each amino acid is added, 00:06:19.09 it waits for a stop and that's how it knows 00:07:14.24 and I'm going to show you one example 00:33:53.06 and use the appearance of such reads 00:37:36.07 And we know that's the case 00:10:04.23 they form interesting 3-dimensional interactions 00:25:41.21 because this is endonucleolytically cleaved. 00:23:09.12 and we'll describe those. 00:00:21.24 to trigger a series of events in the cell 00:03:32.27 And we had studied these factors 00:40:23.21 A particular feature to notice, however, 00:22:27.28 and it had to do with those short reads. 00:29:25.24 bind to the initiator tRNA 00:07:28.28 So, what we did in this case 00:34:36.14 It takes place in an RNA-rich active site 00:25:27.01 spread out along this grid, 00:20:42.26 throughout the genome. 00:26:09.26 with an initiator tRNA bound in the P site of the ribosome, 00:10:39.22 And what we've found is that 00:06:45.28 a number of amino acids are specified 00:32:06.04 by the suppressor tRNA. In her first talk, Green provides a detailed look at protein synthesis, or translation. 00:00:39.00 with a given messenger RNA in a eukaryotic cell? 00:10:41.20 there are never as many as 61 tRNAs in any given cell. 00:37:25.10 that seems to mimic, really, 00:15:18.12 for rescue factors. 00:04:46.12 We knew that Dom34 was a homologue of eRF1 00:11:00.16 we found that in fact that was a preferred biochemical substrate 00:09:32.07 of the entire peptidyl-tRNA complex, 00:31:01.10 in the same strain with the nonsense-suppressor tRNA 00:12:41.04 And how can we go about thinking about that? 00:34:17.26 and I suspect that it will happen in higher eukaryotes. Transcription … 00:11:03.02 for these proteins. 00:08:17.12 with all their components there. 00:13:02.17 the whole face of the tRNA. 00:36:13.10 It brings them together with universally conserved elements. Relate protein synthesis and its two major phases to the central dogma of molecular biology. 00:26:30.04 that leads to another set of ribosomes 00:01:42.27 we're going to have adapter molecules 00:19:19.20 this is another view of the ribosome 00:17:06.28 First of all, we show, here, 00:29:51.18 But the experiment we did The concept of the genome as the complete set of genes in a cell and of the proteome as the full range of proteins that a cell is able to produce. 00:02:53.00 and Non-Stop Decay 00:06:56.00 no matter what combination of three nucleotides you reach, 00:22:35.18 the 30 nucleotide long standard ribosome reads. 00:08:50.01 - this is a deacylated tRNA 00:34:49.09 - the translocating factors - Protein synthesis is the process by which proteins are formed in biological cells. It is made during transcription in the … 00:22:06.04 by the machinery specifically responsible 00:21:23.22 So, now we're going to move on 00:08:07.28 what we did is we took these complexes, 00:29:38.14 GTP hydrolysis takes place on eIF2, 00:31:01.26 If you go too fast, you'll make more mistakes, 00:34:50.16 and they might be typically targeted by the Dom34 system. 00:10:13.03 where the amino acid is going to come in 00:07:26.04 might take you from a lysine to an arginine, 00:22:56.02 However, if we look specifically at the short reads, 00:17:01.26 that catalyzes protein synthesis, 00:07:38.20 a dipeptidyl-tRNA, Translation is the process by which nucleotides, the “language” of DNA and RNA, are translated into amino acids, the “language” of proteins. Both DNA (deoxyribonucleic acid)and RNA (ribonucleic acids) are involved in the process, which is initiated in the cell's nucleus. 00:04:19.08 and we had been studying them biochemically. 00:00:55.08 that tells a ribosome 00:34:57.18 that we're looking at here... 00:05:23.23 Each of those three-letter codes 00:09:29.27 was actually resulting in the release 00:12:03.02 is for recycling of these ribosome complexes 00:41:55.22 translocation... 00:28:17.05 to directly tether to an anti-Shine-Dalgarno motif in the ribosome. 00:24:56.19 and you recognize your AUG, 00:31:46.16 what if we look at this in a more global way? 00:00:25.24 The central dogma, of course, 00:27:18.28 that's related 00:15:02.16 for more than one protein, 00:42:17.12 where the synthetases rarely make mistakes 00:31:57.13 of the codon-anticodon interaction 00:16:57.23 you can see that three nucleotide periodicity emerging. 00:23:47.03 But first, I need to tell you a little bit about the HAC1 gene. 00:29:27.24 in the context of an initiation factor known as eIF2, 00:30:28.04 Elongation is the process by which 00:34:42.23 maybe, that were in this area down here, 00:30:06.08 and therefore translation into the 3'UTR 00:25:38.15 are piled up at this endonucleolytically cleaved junction, 00:00:57.16 known as protein, 00:19:32.08 and you ask, how do they distribute over your transcriptome? 00:17:06.01 that might tell us something new about the function Science 330: 369-72. 00:01:54.27 Another example of a possible problem 00:07:14.08 it ends up typically having a relatively minor consequence, 00:04:59.21 and at the top, interacting with the large subunit of the ribosome, 00:17:59.15 and a large RNA in the small subunit. 00:03:14.06 iteratively adding an amino acid to the growing chain, 00:10:09.24 that a tRNA has to have. 00:21:56.26 which means in a wild type and a knockout strain 00:29:58.12 is they misrecognize stop codons It is the second part of the central dogma in genetics. 00:11:22.15 there are perfect Watson-Crick pairing interactions 00:20:39.09 this is the structure of a yeast ribosome, 00:19:12.11 and facilitates interactions with the tRNAs Biology - DNA and Protein Synthesis. 00:30:59.11 We see that here when we look, again, 00:12:18.05 is a huge part of the magic of translation, 00:39:53.01 in that they have a motif that recognizes a codon 00:17:19.23 What we reasoned is that, 00:06:36.18 Whereas other codons, for example, leucine, 00:05:13.02 we can have a U, C, A, or G, 00:20:59.22 And what we see is, in addition to the protein/RNA layer 00:21:09.29 but it gave us a feeling for the type of result 00:32:02.28 EFTu is going to load the aminoacyl-tRNA into the ribosome. 00:03:04.02 and rescuing the ribosomes 00:05:51.16 we see it here on the left side of the codon table. 00:08:12.03 and carry an amino acid, 00:07:01.15 So, those are some of the key features of the code. 00:27:03.19 and in the absence of this system 00:23:07.19 that I'll refer to as core functions, 00:29:30.15 it's just an average yeast gene - 00:42:19.19 in connecting amino acids to tRNAs. 00:32:50.19 But what I'm going to argue 00:24:47.16 happens in a very continuous process in the cell, 00:29:26.13 is if we take an individual gene - 00:02:27.27 presumably in a primordial world, 00:30:00.14 and they read through stop codons, 00:32:28.06 and it'll be rejected before it's even past that GTP hydrolysis step. As a post-doctoral fellow at the University of California, Santa Cruz,… Continue Reading. 00:02:59.12 nproductive messenger RNAs, Green’s second talk focuses on work from her lab investigating how ribosomes detect defective mRNAs and trigger events leading to the degradation of the bad RNA and the incompletely translated protein product and to the recycling of the ribosome components. 00:22:05.26 and it's also in the occupancy by ribosomes. 00:01:49.10 are going to be attached to the amino acid building blocks By comparing protein synthesis in bacteria and eukaryotes, Green explains that it is possible to determine which components and steps are highly conserved and predate the divergence of different kingdoms on the tree of life, and which are more recent adaptations. 00:15:29.12 has its own Shine-Dalgarno region. 00:00:35.22 The genetic information is found in the form of DNA, 00:39:44.22 As an additional point, 00:33:20.06 about how the ribosome recognizes 00:10:34.00 As I mentioned, three of them are stop codons 00:04:24.06 was that recognition of a bad messenger RNA 00:08:18.17 actually found an activity, an RNA activity in extracts, 00:09:28.05 when interacting with these ribosome complexes, 00:00:48.20 built of similar building blocks, called nucleotides. 00:02:50.21 is focus on two general areas. 00:32:06.12 You can see that there's an equilibrium 00:06:39.18 specifying various peptides 00:12:23.08 that realizes or understands 00:17:10.04 I'm going to tell you that we added another little touch 00:35:29.19 is formed exclusively, really, of RNA components, 00:06:46.12 We can place, for example, 00:12:27.01 and that is the translation of the genetic code. 00:32:19.12 that tRNA is going to sit longer 00:20:10.22 and this gives you a feeling for this, here. 00:25:15.17 continually producing peptides, Kinetic analysis reveals the ordered coupling of translation termination and ribosome recycling in yeast. 00:09:39.25 There are two other stem-loop structures, 00:19:59.18 as well as sequencing biases, 00:36:51.13 Thank you. 00:17:47.21 because we knew that we might... 00:31:16.10 and the ribosome has run to the end of that messenger RNA, 00:14:43.00 when they're ready for protein synthesis. 00:01:02.05 have a start codon 00:20:21.08 is sort of what the bacterial ribosome looks like 00:29:45.16 It's found the AUG and it's ready to go. 00:15:56.22 down a messenger RNA template, 00:11:30.04 the third position is mismatched, 00:04:28.01 So, as I mentioned, there are 20 different amino acids, 00:23:54.04 and you can see again that there are names 00:06:44.24 and other steps in the translation system. 00:35:54.03 This is the growing polypeptide chain. 00:33:18.15 and they tell us something important 00:19:44.27 from the beginning of the open reading frame to the end, 00:33:57.06 as a signature of this process Scientists can also synthesize artificial peptides usi… 00:14:34.18 You can then isolate that 30-or-so nucleotide long messenger RNA 00:02:20.04 which must have been chemically activated in some way, 00:10:27.16 how many tRNAs are there typically in a cell 00:20:01.06 and cloning biases, 00:26:37.06 a beautiful example of what Dom34 does in the cell 00:20:38.20 and so we anticipated that there would be pauses, 00:34:39.08 what you can see here was there was about 5% of the reads, 00:07:20.03 If we compare lysine and arginine, 00:03:34.04 and how they work biochemically 00:27:18.13 to bind to the AUG? 00:06:15.16 And so when a ribosome reads along The production of proteins from the code within DNA occurs in two main stages: 1. 00:12:41.18 they make a mistake about 1 in 10^5 times. 00:35:56.19 This is the aminoacyl-tRNA that's been loaded. The DNA code for the protein remains in the nucleus, but a copy, called mRNA, moves from the nucleus to the ribosomes where … 00:30:53.17 and we'll talk about a number of steps 00:37:49.26 and what we see is domain IV of EFG, 00:14:08.12 by asking where ribosomes accumulate 00:34:33.28 and that's how peptide bond formation takes place. 00:11:04.20 UUC is a phenylalanine codon, 00:32:19.19 reading this polyA tail. 00:06:52.19 and that's what we mean by non-ambiguous. 00:02:51.27 No-Go Decay, 00:16:50.13 that are going to be evaluated by the protein synthesis machinery 00:03:50.26 which is the copy of the double-stranded DNA 00:02:38.16 and what's thought to happen 00:08:44.08 Whereas on the right here, 00:13:48.05 It was a method known as ribosome profiling 00:10:48.04 And a little aside is that these proteins 00:27:16.28 Alright, I'm going to tell you another story, now, 00:07:10.24 such that if there's a mutation 00:16:07.28 and see that the reads distribute to all three frames, 00:34:09.01 of universally conserved nucleotides 00:16:58.18 and finally we get to the ribosome. 00:35:08.26 suggesting that in fact 00:41:00.11 Much like the termination factors, 00:42:03.00 The most different steps Dehydration reactions are a subset of condensation reactions where two functional groups combine to form a covalent bond along with the release of a small molecule such as water, HCl, methanol or acetic acid. 00:02:28.02 and in that case the ribosome 00:27:40.07 and says, "This is a problem. 00:38:19.09 we've translated all the way 00:31:50.20 is a GTPase, 00:27:09.08 for the model for No-Go-Decay, 00:17:49.05 based on the biochemical activity of Dom34 and Hbs1, 00:11:12.25 The anticodon of this tRNA Craig N, Green R, Grieder C, Storz G, Wolberger C, and Cohen-Fix O. Molecular Biology Principles of Genome Function, 2nd Edition, Oxford University Press (2014) Chapters 11 and 12. 00:04:41.26 can cover the 20 amino acid complexity, 00:29:04.26 that were outlined several slides ago. 00:07:44.28 for one round of protein synthesis - 00:33:47.13 we see that these adenosines 00:25:51.04 and that's really the key to finding the AUG in bacteria. 00:15:42.08 and we'll describe that in a number of slides. 00:15:54.11 are moving three nucleotides along at a time 00:03:43.06 a long stem-loop structure 00:23:16.18 for part of the complexity of higher-order gene regulation 00:02:35.06 and encounter a polyA tail. 00:08:21.02 So, at the top of the gel, 00:31:58.08 And there they are, 00:04:37.12 that the ribosome is what determines 00:00:09.12 I'm at the Johns Hopkins University School of Medicine 00:22:51.04 There's no differences in their distribution. 00:00:33.19 that perform most of the functions of the cell. 00:14:43.20 You get hundreds of millions of reads 00:40:25.14 is that the way they solve chemistry 00:20:10.29 there were no obvious pauses in this gene, 00:02:31.13 which is now a very sophisticated 00:00:18.22 So, protein synthesis is also known as translation 00:24:20.06 and we'll talk about that. 00:01:00.11 So, we see that the process of translation 00:21:12.14 but they likely are going to be 00:05:43.03 and we see that protein synthesis, 00:23:43.26 and their different mechanism of finding the AUG start site. 00:36:32.21 a nucleophilic displacement. 00:16:46.18 And those are key features 00:40:29.28 They both perform the chemistry 00:08:35.23 So, ultimately, this RNA activity 00:02:00.12 If the messenger RNA picked up a cleavage 00:06:43.04 So, this is what we mean by a redundant code: During protein synthesis, amino acids arrange in a linear fashion through an intricate interaction between ribosomal RNA, transfer RNA, messenger RNA and a variety of enzymes. 00:02:49.08 that we refer to as non-stop decay. 00:31:39.14 or into the decoding center. 00:29:56.14 by this factor known as IF2, 00:15:18.27 they have a stop codon associated with it, 00:17:15.14 that the full-length ribosome footprints 00:36:52.08 to open up the aminoacyl site, here, 00:32:16.20 in the decoding center. 00:20:30.16 In fact, there's some additional proteins 00:09:54.08 is they were recognizing ribosomes 00:13:49.22 that allows one to systematically look 00:08:22.17 to radioactively-labeled amino acids, Shoemaker, CJ, Eyler, DE, Green, R. (2010) Dom34:Hbs1 promotes subunit dissociation and peptidyl-tRNA drop-off to initiate no-go decay. 00:06:05.07 from the yeast Saccharomyces cerevisiae. 00:10:29.18 in order to recognize these 64 codons 00:12:35.04 Which messenger RNAs are typically targeted in a cell? 00:01:40.28 early in the open reading frame. Protein synthesis is a biological process that allows individual cells to build specific proteins. 00:04:36.00 It seemed like a very logical idea 00:21:48.01 and what you can see is a very uninteresting pattern 00:23:20.12 and we'll talk about a number of these factors 00:02:10.26 and I think that's the best way to begin thinking about 00:41:48.02 Protein synthesis is an RNA-driven process. 00:05:38.26 it was related to a termination factor, Translation (Protein Synthesis) definition The translation is a process of synthesizing proteins in a chain of amino acids known as polypeptides. 00:12:19.19 and so we wanted to ask next a more general question. 00:28:15.14 is they use the Shine-Dalgarno 00:04:34.10 that decides whether a message is good or not. 00:16:28.22 here, to the beginning of the gene, 00:14:01.04 in yeast cells for example, 00:11:25.22 However, in the case where the same tRNA 00:27:32.20 and it turns out that the bacterial ribosome, 00:02:45.11 the way in which it catalyzes those events. Within the process are involved both DNA (deoxyribonucleic acid) and different in their function ribonucleic acids (RNA). It takes place in the ribosomes found in the cytosol or those attached to the rough endoplasmic reticulum. 00:09:05.21 here - not a peptide band - 00:36:06.12 and it's properties of the ribosome 00:15:30.16 from wild type yeast and from Dom34 mutant yeast 00:35:37.00 that's why it's embryonic lethal in higher eukaryotes, 00:23:40.02 because it ends up being a very clear, 00:36:20.26 that the incomplete protein product needs to be targeted for degradation, Proc Natl Acad Sci USA 108(51):E1392-8. 00:10:36.02 that are not recognized by tRNAs, MCB-1052331. 00:30:32.14 So, this is evidence that 00:01:30.12 That is, instead of 00:04:48.10 and that's highlighted by this structural view here. 00:41:43.29 that evolved long before the divergence 00:33:55.20 in the middle of open reading frames 00:37:22.24 we see that there's a protein domain on EFG 00:03:01.04 getting rid of the messenger RNAs, 00:19:37.27 here, PGK1. 00:11:39.24 And given that there are many ribosomes 00:02:22.27 is that the messenger RNA might not actually have a stop codon, 00:06:25.10 are specified by just one codon. 00:37:30.20 And so, from that look at the crystal structure, 00:08:03.24 rather than the amino acids. 00:30:02.29 where the small subunit is joined by the large subunit 00:05:48.20 The triplet codon that specifies methionine is AUG; 00:31:11.02 we see yellow reads 00:04:31.15 or the catalyst, or the macromolecule, 00:16:56.24 So, there are the messenger RNA building blocks, 00:35:32.12 which helps us to understand 00:33:06.09 - the green arrows - 00:28:30.20 or metagene analyses 00:11:54.04 and this explains how 30-40 tRNAs 00:10:27.26 was codon independent. 00:11:38.25 that makes the nucleotides face one another like this, 00:06:14.17 We had tRNAs, messenger RNAs, Rachel Green received her BS in chemistry from the University of Michigan. 00:42:37.08 And with that I'll stop. 00:10:52.18 when the messenger RNA template, here, tends to be short. 00:13:36.16 the orange amino acid, 00:33:12.22 RNA14 is a gene in yeast, 00:36:57.02 and the next round of elongation. 00:09:32.20 There's always a CCA - 3' terminal CCA tail, 00:42:12.06 And in a number of points 00:23:42.26 positive effect of Dom34 in yeast, 00:06:47.27 by more than one codon. 00:14:12.05 is removing an amino acid 00:03:07.24 which you'll see is going to be called finding the AUG, 00:25:18.18 - so those peaks that we isolated for two ribosomes in a row - 00:24:16.28 and they've discovered similar ways of doing things, but different as well, Research Articles 00:32:26.22 and an endonuclease coming behind. 00:09:58.24 that led to the release 00:18:51.08 This is a fragment that's been characterized 00:00:44.29 has to be transcribed into a different form 00:06:17.18 to the end of a coding region, 00:09:00.26 in mRNA surveillance, 00:03:28.20 by termination factors in eukaryotic cells 00:24:21.03 in the endoplasmic reticulum. 00:14:44.22 If we look on the left we see 00:29:01.12 This scanning takes place 00:20:50.14 exactly where there are histidine codons 00:20:25.02 The next one that we see here is the archeal ribosome, 00:13:04.06 including, for example, 00:25:57.28 Moreover, when we looked, actually, 00:02:29.14 might actually get all the way through 00:28:54.09 and that kind of propagates along the length 00:36:39.10 was done by Chris Shoemaker, 00:04:09.06 and finally about some of the many factors 00:37:02.08 It's a GTPase 00:35:18.08 and we see the active site here. 00:40:00.05 are really quite different in bacteria and eukaryotes, 00:03:17.03 the growing protein chain, 00:29:14.12 we think the messenger RNA tends to exist like this 00:08:28.19 it runs as a big 80S complex. 00:24:39.26 in the two different systems. 00:12:05.02 which is that the amino acids, 00:42:34.28 which could be the subject of a subsequent lecture. 00:10:52.01 and we refer to an event known as wobble 00:19:43.09 distribute all along its length, 00:35:58.24 Again, the adenosine at the end of the tRNA, 00:28:04.11 and we're not quite sure what might happen to these ribosomes. 00:23:38.01 whereas these other eukaryotic-specific factors 00:11:52.16 only at the third position, 00:17:14.14 is extending from the messenger RNA up to the polypeptide chain. 00:18:06.02 so we were generous in slicing our fragments from a gel. 00:07:40.07 So, these are nice features that are built into the codon table, 00:18:22.19 the ribosome typically has three tRNA binding sites, 00:22:12.02 It's a gene known as Hac1. 00:22:25.25 about Dom34 function in the cell, 00:19:55.24 And that's what we're going to talk about next. 00:02:05.16 So, this is an iterative, linear march 00:28:39.02 or three, or, or five, and so on. 00:36:33.14 And with that I'll mention the main players in my lab 00:37:56.18 and likely functions much like a pawl in a motor 00:33:32.12 is being interpreted. 00:03:42.24 We're going to start talking about the genetic code. 00:38:13.27 Okay, now for the final steps: 00:09:06.06 that we refer to as the anticodon This material is based upon work supported by the National Science Foundation and the National Institute of General Medical Sciences under Grant No. 00:30:04.20 at the some level, 00:31:13.29 and it's probably the most abundant protein in biology. 00:11:24.22 at a particular place in a messenger RNA, 00:03:59.22 in a process he called No-Go-Decay, 00:12:32.04 the general biological significance 00:07:51.14 we see that the amino acid is labeled. 00:24:54.04 It's an open reading frame 00:18:51.14 a crystal structure of the ribosome Opportunities for skills development. 00:07:19.26 about Dom34 and Hbs1 function, 00:31:41.10 That process is outlined here, 00:33:50.14 in these strains - the Dom34-delta strain - 00:00:46.06 come out of the nucleus with a cap 00:10:32.04 that specify what's in a protein? 00:28:45.28 and in fact the scanning model 00:41:15.28 and the result is that, in an energy-dependent reaction, 00:01:18.22 or a polymer of amino acids that we refer to as proteins. 00:34:53.15 And what I can tell you is if we knock out Dom34... 00:21:09.28 They kind of look crazy, and it's not clear what they do, 00:27:34.26 the small subunit of the ribosome, 00:32:45.25 because we've put in a nonsense suppressor tRNA 00:19:34.13 How do they distribute along a messenger RNA? 00:00:23.24 this is the final step in the central dogma. 00:04:05.14 Then we're going to talk about the catalyst of this event, 00:34:31.27 is transferred to the pink tRNA, 00:41:33.14 First, the translation components 00:23:54.16 it encodes a transcription factor that's involved in the unfolded protein response 00:12:51.23 is something known as proofreading. 00:16:26.18 if you align all of the start codons, 00:14:35.19 in the bacterial and eukaryotic cell, 00:30:54.14 to see signs of this endonucleolytic cleavage 00:17:54.02 and only one-third of the mass is proteins. 00:41:20.25 releasing the messenger RNAs, the tRNA, 00:14:46.13 the elements of a bacterial messenger RNA, 00:22:24.01 that showed us something new and exciting 00:25:25.05 We see a messenger RNA template, here, 00:15:27.02 And you see that each specific open reading frame 00:30:42.05 And then there's a step we refer to as translocation, 00:20:12.29 or problems, that led to Dom34 action. 00:25:19.15 when we look at this EM (electron microscopy) image of translation in a cell 00:04:18.00 the genetic code really is at the heart of translation. 00:25:45.03 Under normal circumstances, 00:33:47.26 What I can tell you is that if we look broadly at yeast, 00:33:16.14 that are known to be prematurely polyadenylated. 00:39:31.14 We see that's true when we look at the way they bind to the ribosome.
