Another facet of ubiquitylation: death

J Mol Cell Biol. 2009 Dec;1(2):80-1. doi: 10.1093/jmcb/mjp019. Epub 2009 Sep 30.

Abstract

Ubiquitylation of caspase-8 by the Cullin3 E3 ligase allows its translocation to cytosolic aggregates in the cell by p62/sequestosome-1, increasing caspase-8 activation and thus leading to TRAIL-induced cell death.
