Carbon catabolite repression in Aspergillus nidulans involves deubiquitination.

Abstract excerpt

The best studied role of ubiquitination is to mark proteins for destruction by the proteasome but, in addition, it has recently been shown to promote macromolecular assembly and function, and alter protein function, thus playing a regulatory role distinct from protein degradation. Deubiquinating enzymes, the ubiquitin-processing proteases (ubps) and the ubiquitin carboxy-terminal hydrolases (uchs), remove...
