This is exciting and opens new avenues for studying the proteasome-ubiquitin system. I am now awaiting K11 ubiquitin-specific probes ;)

Here’s a brief teaser for our latest preprint reporting the first structures of the K11/K48-branched Ub chain bound to the human proteasome: https://t.co/illzy1JT4X Check the full text for more details: https://t.co/D9BMaW7poF Thx to @asibc512 for making this possible!

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

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.
