Organism
Caenorhabditis elegans
Function
Probable core component of multiple cullin-RING-based BCB (BTB-CUL3-BTB) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed:13679922). Probably acts as a scaffold protein which may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme (PubMed:13679922). Required to target mei-3/katanin for degradation at the meiosis to mitosis transition via its neddylation and deneddylation (PubMed:12781129). Functions in ubiquitin-mediated degradation of CKIs to target cki-1 for degradation (PubMed:12781129). Regulates microtubule stability in the early embryo (PubMed:12781129). In body wall muscles, involved in the organization of myosin thick filaments, likely by regulating the degradation of microtubule severing protein mei-1 downstream of unc-89 (PubMed:22621901).
Similarity
Belongs to the cullin family.
