Can we program a kinase like a switch? Inspired by natural autoinhibitory complexes, we designed miniproteins against active- and inactive-like conformations of Focal Adhesion Kinase. Depending on the targeted state, the resulting binders either activated or inhibited the kinase.

During the last #WorldCup, I randomly found my long lost Mexico '86 #Panini sticker album. And with England at the Azteca next, I thought you might like to see it. It was the first World Cup I can remember, and I can hardly believe it was 40 years ago. Let's hop into the DeLorean, shall we?... 🧵

Yorkshire, indeed the world, has lost some of its colour today. Garrowby Hill, a Yorkshire landscape by David Hockney, 1998. So long, David.

Delighted that this is now out in its final form! 🥳 It's a fun story about an EF hand that doesn't bind Ca2+, but instead works as a ubiquitin-binding domain. Huge thanks to the rest of YK lab, the @mrcppu.bsky.social, and our collaborators (@sebastianglatt.bsky.social)!

Lee Armstrong, Yogesh Kulathu @kulathu.bsky.social and co-workers show that MINDY3's EF-hand domain is a novel #ubiquitin binding domain. It not only enables chain-length-dependent deubiquitination but also binds to DNA repair factors RAD23A/B. -> link.springer.com/article/10.1...

"Let's say this Twinkie represents the outright racists in the UK when that BNP list got leaked in 2008. According to this morning's sample, it'll be a Twinkie....35 feet long and weighing approximately 600 lbs"

A fellow of the Royal Society slashed funding for disease prevention, leading directly to the deaths of uncounted children. He promotes white supremacy and is actively encouraging racist violence in the UK. But he's Elon Musk, a billionaire. So the Royal Society does nothing. @royalsociety.org

I have to say, listening to the Today programme dedicate an entire (context free) section about whether migrants are more likely to be convicted criminals *the morning after* hundreds of non-migrants of my own ethnicity committed a pogrom is blood boiling.

You know the most destructive molecule for my experiments is Air? ITC thermogram shifts? Bubble. Gel refuses to run properly? Bubble. Crystallization ruined? Bubble. Mysterious signal artifacts? Also bubble. My troubleshooting career = fighting microscopic air pockets with a pipette tip. #origichals

still not quite over the fact that i watched 15 year olds get sued for millions of dollars for downloading twelve songs and now we all have to accept AI slop because every tech company in the known universe decided that IP laws don't exist now that they're inconvenient for them
