Protein Information (annotations from UniProt)

Database IDHIV0004437
UniProt IDQ93034
Primary gene name(s)CUL5
Synonym gene name(s)VACM1
Protein nameCullin-5
Protein functionCore component of multiple SCF-like ECS, Elongin-Cullin 2/5-SOCS-box protein E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The functional specificity of the E3 ubiquitin-protein ligase complex depends on the variable substrate recognition component. ECS(SOCS1 seems to direct ubiquitination of JAK2. Seems to be involved in proteosomal degradation of p53/TP53 stimulated by adenovirus E1B-55 kDa protein. May form a cell surface vasopressin receptor.
