Our preprint on the first glimpse of how the human proteasome recognizes a K11/K48-branched ubiquitin chain is out. This work reveals a new multivalent ubiquitin binding mode by the proteasome that could serve as priority checkin signal for proteolysis. https://t.co/Sk2ERBDb9B

Everyone (including me :) is hyped up about the new AF3 today, so letās mix it up with some other cool science updates from yesterday:
The floor is lava! š„ Webb may have detected atmospheric gasses around molten 55 Cancri e, 41 light years from Earth. Itās the best evidence to date for a rocky planet with an atmosphere outside our solar system! https://t.co/8pl9VAIS1M

Love it :D @wojtek_pokrzywa have an idea to level up the difficulty: how about adding branched K11/K48 Ub chains into the game scenario? ;D

A lot is happening at the interface of AI and cryoEM. It's great to see another method aiming at resolving structural heterogeneity of the sample as this is where the cryoEM really shines.
1/ Very excited to present cryoSTAR, a novel approach for continuous heterogeneity in SPA cryo-EM. In brief, cryoSTAR leverages the prior knowledge from a user-given atomic model to better find dynamics in the final reconstruction. https://t.co/WaaTUnMQRM
