Ramping up degradation for proliferation

Nat Cell Biol. 2016 Feb;18(2):141-2. doi: 10.1038/ncb3306.

Abstract

The control of proteasome-mediated protein degradation is thought to occur mainly at the level of polyubiquitylation of the substrate. However, the proteasome can also be regulated directly, as now demonstrated by a study in which DYRK2-mediated phosphorylation of the 19S subunit Rpt3 is found to increase proteasome activity.
