Here are the success rates of de novo pipelines based on which designs I could actually identify the methods for.

The ribosome synchronizes folding and assembly to promote oligomeric protein biogenesis Large oligomeric proteins constitute a major fraction of proteomes, but are difficult to refold in vitro, raising the question of how cells direct their biogenesis. Roeselová and Shivakumaraswamy et a...

Our latest cotranslational folding story is now published @cp-molcell.bsky.social. Really cool (I think) new ideas about how exactly the ribosome directs folding and assembly to make sure complicated proteins mature efficiently in cells.

Mirdita Lab - Laboratory for Computational Biology & Molecular Machine Learning Mirdita Lab builds scalable bioinformatics methods.

My time in @martinsteinegger.bsky.social's group is ending, but I’m staying in Korea to build a lab at Sungkyunkwan University School of Medicine. If you or someone you know is interested in molecular machine learning and open-source bioinformatics, please reach out. I am hiring!

Second preprint of the year in which @sarahgersing.bsky.social from @rhp-lab.bsky.social mapped the effects of >7500 variants in glucokinase (GCK) on the interaction with the glucokinase regulatory protein so that we now have a 3D GCK scan (abundance, interaction, activity)

This one was quite the journey! The paper describing the #ChlamyDataset is finally out and on the cover of Mol Cell!

This beautiful rendering made by co-author @jessheebner.bsky.social and Holly Peterson shows an instance of mitochondrial fission found in the dataset 😍

Assessing the validity of leucine zipper constructs predicted by AlphaFold AP-1 transcription factors are a network of cellular regulators that combine in different dimer pairs to control a range of pathways involved in differentiation, growth, and cell death. They dimerize...

This was interesting and fun to do… seems Alphafold and the like have learnt what a Leucine zipper looks like… but not really.🤔 interesting that a fully synthetic leucine zipper that couldn’t possibly assemble looked pretty probable. 🧶🧬

Brand new preprint from my lab, showing that TnpB, the ancestor of Cas12, acts as a gene drive in plasmids! And it turns out in conjugative plasmids that it acts as a primitive anti-self defense system, providing a potential link between its transposon effect and becoming CRISPR!

New preprint! We measured temperature- and pH-induced aggregation for over 18,000 natural and de novo designed protein domains!

Tired of knowing what you are looking for in your tomograms?
Why not try bluesky-less Frosina's new self-supervised algorithm for semantic segmentation and particle picking for #teamtomo (includes a new denoiser without the need for odd/even tomos)

Code is on GitHub if you want to try it out

A few py2Dmol updates 🧬

Integration with AlphaFoldDB (will auto fetch results). Drag and drop results from AF3-server or ColabFold for interactive experience! (1/4)

#1 lesson I give to protein designers for wet lab purposes : Please design with a Trp and/or multiple Tyr. Please do not design with 10 cysteines.

Has this idea of sampling neighbors from an inverse cubic distribution been used in protein structure GNNs at all since the idea was first presented in the Chroma paper ~3 years ago? I thought it was incredibly clever and expected it to catch on, but haven't seen it since

Efficient protein structure generation with sparse denoising models - Nature Machine Intelligence A small and fast diffusion model is presented, which is able to efficiently generate long protein backbones.

We used a similar random neighbour scheme in salad (www.nature.com/articles/s42...), with 16 neighbours by residue index, 16 neighbours by distance and another 16 using the 1/d^3 scheme from Chroma, which worked reasonably well for protein backbone generation.

hey bsky! excited to share what i've been working on for a few years now.

Can an AI tool help us better understand the origins of cancer?

Researchers from EMBL's Korbel Group have developed a new AI method – MAGIC – which, through a game of molecular laser tag, is shedding light on how chromosomal abnormalities form in cells.
