On BlueSky I am a research scientist with a passion for the structure and mechanism of macromolecules - but at Instagram I cook and at Facebook I am into Greek politics.

7/11 onwards, the best bit ☺️

Read the whole thread by @daaninthelab.bsky.social : a power walk to a great adventure! Very proud of her and @rborza.bsky.social and the whole team!

CryoEM analysis of the Zincore bound to ZFP91 onto the DNA revealed a striking complex: instead of recognising an effector domain, Zincore binds to multiple DNA-bound ZNF domains directly, which revealed two peculiarities: 7/11 @rborza.bsky.social @tassosperrakis.bsky.social

🚨New Article Out!!

📢 In our latest work, we propose a Three-Point Lock binding mode for ATX inhibitors 🔒

🚀 This approach may represent the final piece in the puzzle of known binding mode types — and could have therapeutic relevance

♥️ Thanks for your support

Fast-forward: Ida de Vries revisited the old crystal structures, made new discoveries, and revived the project. Published today, this work may not change the world, but it reflects science's quieter side: missteps, small victories, and perseverance. Here's to the bittersweet journey of discovery.
JBP1 and JBP3 have conserved structures but different affinity to base-J
Base-J (β-D-glucopyranosyloxymethyluracil) is an unusual kinetoplastid-specific DNA modification, recognized by base-J containing DNA (J-DNA) binding …

During the COVID era when I was compulsively scrolling through the toxic wasteland of Tweeter I spotted this: A common contaminant? Turned out, we’d been analyzing a bacterial protein (same MW and DNA binding affinity) all along. Experimental science can be humbling, even crushing at times.

Few years ago, our collaborators on the "base J" project identified the JBP3 protein. We had determined the crystal structure of the DNA-binding domain, but we could never make sense of the cryo-EM reconstructions of full-length JBP3: nice single particles, but AlphaFold models did not fit the maps.

Thrilled to present Alphabridge in the Computational Chemistry session at #NWOChains! We aim to facilitate researchers to analyze interacting interfaces in predicted biomolecular structures. Honored to share insights with top chemists in the Netherlands. 🚀🔬 Preprint: www.biorxiv.org/content/10.1...

Greece got exactly 0 ERC consolidator grants this year.

0 grants to mid-career outstanding scientists for curiosity driven research at the highest level.

Maybe a statistical fluke?

Or a result of chronic national underfunding, insane bureaucracy, unfairness, opacity, nepotism, and low income?
