If your ribosome stalls, who you gonna call? RIBOSOME-ASSOCIATED QUALITY CONTROL (RQC)! Let me have a go at explaining RQC and NO-GO mRNA processing! "protein machinery de-paper-jamming" 👉bit.ly/2KWfcPo
#365DaysOfScience #biochemistry #scicomm #realtimechem
The antibiotic Gentamicin acts like a “love potion” that lets amino acids “marry” partners other than their soul mates w/a love is so strong, they don’t want to move off the altar. Learn how 👉 bit.ly/2Pw4vSd
#365DaysOfScience #biochemistry #scicomm #realtimechem
If your ribosomes get into a crash when making proteins, you want to check that involved parties are ok before you try to resell them! RQC uses clever “sorting mechanisms” to reuse vs salvage parts 👉 bit.ly/2GACRzp
#365DaysOfScience #biochemistry #scicomm #realtimechem
UBIQUITIN's like pre-addressed shipping label that gets attached to proteins your cell wants to get rid of. UPS (Ubiquitin Proteasome System) delivers them to “trash incinerator” called PROTEASOME 👉 bit.ly/2VxIZ5c

Me - strange? Nonsense! NONSENSE MEDIATED DECAY provides a way to get rid of early stop-signed mRNA! And I hope yoUAGree it’s immature to start lAUGhing at PREMATURE STOP CODONS! 👉 bit.ly/2GFSdmc
#365DaysOfScience #biochemistry #scicomm #realtimechem
But officer, I didn’t see a stop sign! What if there’s NO stop codon? This triggers a process called NONSTOP DECAY (NSD) 👉 bit.ly/2WiYfzO

Caps off to mRNA decapping! use to get through cellular security, then remove to to take advantage of that security -> prevent protein “baked goods” from being made & expose recipes to shredders!👉 bit.ly/2GY0wKh
#365DaysOfScience #biochemistry #scicomm #realtimechem
We owe much of our understanding of these mRNA decay processes to a brilliant biochemist named Dr. Eliza Izaurralde, whom we lost much too soon. You can learn more about her in this #WiSEWednesday profile from @CSHL_WISE: bit.ly/2Jewy7N

How to MEASURE protein production productivity? Different ways. How many copies of recipe are made? in circulation? actually being used? are the final products sticking around? Read more 👉 bit.ly/2vPQ56J
#365DaysOfScience #biochemistry #scicomm #realtimechem
I didn't have time/space to go into it there, but the same original recipe can be edited different ways to give you different variations. This is called alternative splicing & evolution can combine parts of recipes (exon shuffling). You can learn more here bit.ly/2AsVdjG
Most RIBOSOME FOOTPRINTs aren’t quite this big… but they still are useful to see what proteins a cell’s making, how quickly, and whether (and where) there are any “holdups” 👉 bit.ly/2DTndP8
#365DaysOfScience #biochemistry #scicomm #realtimechem
Science meetings can be like geek Disneyland - so let’s talk about POLYSOME PROFILING (way to look at protein production) in terms of Disneyland trying to see how popular its diff rides are 👉 bit.ly/2HcbBYv

Science is sometimes stressful & even superheroes struggle! have a great mentor who encouraged me 2 do something fun 🙏 So graphics 4 me 2 remind myself why I don’t give up & review of EXPERIMENTAL DESIGN 4u 👉 bit.ly/2VoXt8a
#365DaysOfScience #biochemistry #realtimechem
What's a ribosome look like? I ❤️ this sculpture, but it’s far from high-RESOLUTION. But today I got to hear a great talk from Venki Ramakrishnan, who provided us w/much closer look w/CRYSTALLOGRAPHY👉 bit.ly/2Jxtcgn
#365DaysOfScience #biochemistry #scicomm #realtimechem
If Disneyland’s happiest place on earth & each of our cells is like a copy of of it, we should all b super happy right? But “park security” - “cop car” guided by miRNA can shut down rides at will 👉 bit.ly/2Q0vNAp
#365DaysOfScience #biochemistry #scicomm #realtimechem
micro-RNAs (miRNAs) direct protein-recipe-destroying machinery at specific “target” recipes (mRNAs) to prevent production of specific proteins. What’s this tiny RISC-taking superhero’s origin story? 👉 bit.ly/2JAy9Vw
#365DaysOfScience #biochemistry #scicomm #realtimechem
Lately I feel like I keep getting knocked down on my PhD journey. But sometimes scientists celebrate knock-downs, when it’s a gene getting knocked down with siRNA or shRNA that is 👉 bit.ly/2VYTZJ8
#365DaysOfScience #biochemistry #scicomm #realtimechem
If u want 2 *interfere* w/protein production w/o messing w/the gene, u can turn to RNA INTERFERENCE to lessen its protein If instead u want to permanently knock gene out CRISPR/Cas9 offers a route 👉 bit.ly/30mHjuE
#365DaysOfScience #biochemistry #scicomm #realtimechem
If your Cas & PAM match, onto DNA Cas'll latch & use its sgRNA to take a look around where it has bound. If the guide matches too, stuff Cas will do. But if the sequence ain’t right, Cas will alight!👉 bit.ly/2HlCKJG
#365DaysOfScience #biochemistry #scicomm #realtimechem
If u want to study a protein on its own, you’ll want to make a MOLECULAR CLONE Cuz subtle effects can b hard to tell when u make changes to genes inside a cell Gene editing cell-bio vs biochem style👉 bit.ly/2EfCycW
#365DaysOfScience #biochemistry #scicomm #realtimechem
🎶 You don’t know what you’ve got till it’s gone 🎶 How do you know if a protein isn’t doing what it’s supposed to do if you don’t know what it’s supposed to do? FORWARD GENETICS & REVERSE GENETICS 👉 bit.ly/2W5hGzt
#365DaysOfScience #biochemistry #scicomm #realtimechem
🎶 CRISPR’s got a long list of ex-invaders, they’ll tell you Cas9 cut their DNA. But CRISPR’s got a blank space, baby, & phage, it’ll write your name! 🎶 How bacteria use CRISPR for adaptive immunity👉 bit.ly/2JQ1Baq
#365DaysOfScience #biochemistry #scicomm #realtimechem
If a biologist talks abt swapping out cassettes, they’re probably not referring to Walkmans! CRE-LOX RECOMBINATION has had longer stay cuz it offers a way to swap pieces of DNA 👉 bit.ly/2HtdAcm & more pics below

Pure proteins! Refresher on what occupied my day - size exclusion chromatography (SEC) (aka gel filtration) and SDS-PAGE.👉 bit.ly/2EphbGt
#365DaysOfScience #biochemistry #scicomm #realtimechem
I hope it’s o-Ka if I use Kd and not Ka when telling you about BINDING AFFINITY and how it’s kinda like taking a biochemical “census” of how many molecular “singles” versus “couples” there are. 👉 bit.ly/2JyBbuj
#365DaysOfScience #biochemistry #scicomm #realtimechem
You can’t get too perky when you see a protein peak until you run an SDS-PAGE gel & let the protein(s) speak! It may look like it’s pure but how can you be sure? PROTEIN CHROMATOGRAPHY museumified 👉 bit.ly/2VKBJz0

A very special #365DaysOfScience - my first official post as Student Ambassador for the @iubmb!
If you’ve seen my lab bench in middle of a protein prep, u know I can make quite a mess, but when it comes to the protein itself I’m a stickler for cleanliness. What’s actually going on in an AKTA?
👉 bit.ly/30LklxG
#365DaysOfScience #biochemistry #scicomm #realtimechem
What’s a typical protein purification workflow? How do we select what stays and what goes? Is the prep going well? How can I tell? Disappearing bands on an SDS-PAGE gel. More pics bellow & text 👉 bit.ly/2VMELTe

Through a cuvette the spectrophotometer allows us to peer & measure concentrations w/help of Beer! Beer’s law lets you convert between concentration of a dissolved thing & how much light it absorbs 👉 bit.ly/2RmRHyo
#365DaysOfScience #biochemistry #scicomm #realtimechem
Even w/limited sample, spectroscopic fun doesn’t have to stop - measure concentrations using a NanoDrop! From a little drop of liquid on pedestal, surface tension makes a cuvette-less column - cool! 👉 bit.ly/2KZ8vKQ
#365DaysOfScience #biochemistry #scicomm #realtimechem
Do you listen to your spectrograph peaks when they try to speak? That peakiest peak *might* tell you concentration, but rest of spectrum can tell you about contamination! Are you in this situation? 👉 bit.ly/2KtUbL3
