Popis: The tumor suppressor FBW7 is a substrate adaptor for the E3 ubiquitin ligase complex SKP1-CUL1-F-box (SCF) and itself a target for ubiquitylation. Here, the authors show that TRIP12 mediates branched K11-linked ubiquitylation of FBW7, to regulate its stability and thus abundance of a subset of SCFFBW7 substrates.
