Presenting a model for proteasome condensate formation in which shuttle factors play a critical role. ↔ 💧
Kenrick Waite and team #KUMedCenter show that shuttling factors Rad23 and Dsk2 contribute to the localization of proteasomes in condensates - a process that Ddi1 counteracts. #preprint

Global histone H2B degradation regulates #insulin/#IGF signaling-mediated nutrient stress
The #ubiquitin-#proteasome system regulates #histone #H2B exchange in mammalian cells and in C. elegans during development and starvation.

First #preLight post from Aniruddha Das.
Aniruddha picked a #preprint from the #AOri_lab and team in which proximity labelling is used to identify interactions between the #proteasome and membrane-associated proteins or transcription factors.

Very excited to share our latest published #cryoEM work on the #microsporidian #proteasome with all its proteolytic sites inhibited simultaneously by a PI31-like peptide!! Fantastic job from Nathan, Kai, Rahel, and Dennis, and collaboration with Charlie (@CT_CAES)!
