Our work on the role of the proteasome in developmental tempo is out!!!! 🐭⌛️👤⏳ Six years after identifying an association between protein stability and developmental tempo, we now demonstrate a causal link between protein turnover and developmental tempo through proteasomal degradation

Developmental Cell@cp-devcell.bsky.social

Online now: Proteasome-dependent protein degradation shapes developmental tempo in mouse and human neural progenitors #biology #science

dlvr.itProteasome-dependent protein degradation shapes developmental tempo in mouse and human neural progenitorsWhy do mammalian species develop at different speeds? Nakanoh, Stamataki, et al. show that mouse neural progenitors have faster protein synthesis and proteasome-mediated degradation than human. Manipulating proteasome activity alters the pace of neural development, implicating protein turnover in the evolution of developmental tempo.
