This October I’m drawing 1 molecule a day inspired by proteins in pdb @rcsbpdb.bsky.social

Day 7
Prompt STARFISH
Pdb: 6KG7

Starfish relies on sensory information.
This is Piezo 2 - mechanically activated ion channel responsible for the sense of touch.

Next: RECKLESS

You know, I agree. How about in 2027 we feature ubiquitin in all prompts? Maybe an occasional E3 or a DUB :)

Day 5
Prompt DEER
Pdb 4YXH

Two molecules of a deer prion protein decorate its head. Misfolded prions can make other prions to misfold causing neurodegenerative diseases in mammals.

Next: PIERCE

Day 4
Prompt MURKY
Pdb 8T1M

Domain with unidentified function 1842 from pathogenic bacteria (thanks Leah)

There are many proteins with known structures but their function remains murky.

Next DEER

Day 3/31
Prompt CROWN

Coronavirus spike protein. The crown sits on one of its three receptor-binding domains - a key element for successful infection.

Pdb: 6ZWV

Next prompt is MURKY and I’m at loss

Prompt MUSTACHE
Pdb 2QZI

Let’s start with something fun:
Mr. Potato head’s ‘stache is made of Androgen Receptor that binds testosterone and helps maintain his male phenotype

Next prompt: WEAVE

I was lucky today to finally have a chance to visit RCSB PDB @rcsbpdb.bsky.social at Rutgers. Special thanks to Stephen Burley for hosting and Jason Kaelber for the tour of the facilities.

It’s almost October!
I plant to participate in inktober challenge again this year. One protein drawing a day for 31 days. I would LOVE your suggestions!
Check out the prompt list and nominate a pdb of a protein for me to draw that could be a good fit for any of these prompts.
Wish me luck!

Functional spectrum of USP7 pathogenic variants in Hao–Fountain syndrome: Insights into the enzyme’s activity, stability, and allosteric modulation | PNAS

Hao–Fountain syndrome is a rare neurodevelopmental disorder caused by mutations in the deubiquitinating enzyme Ubiquitin-Specific Protease 7 (USP7)...

Beautiful work! Fascinating to see USP7 in active conformation without ubiquitin or the C-tail helping it out. A lot to think about.

Irina Bezsonova @irinabezsonova.bsky.social · Sep 2

Wow! Take a look at this beautiful structure. So excited to see the entire USP7 there.

Thomä lab @labthoma.bsky.social · Jul 31

Congrats to all the authors on our latest work! We reveal how p53 interacts with chromatin and show, via ubiquitin-related factors USP7 and E6-E6AP, that only specific cofactors can co-reside on nucleosomes together with p53.

New drawing!
Ubiquitin-specific protease 7 (pdb 4M5W)
It’s been a while since I last drew anything. Forgot how fun it is.
