Protein Information (annotations from UniProt)

Database IDHIV0000448
UniProt IDQ86VP6
Primary gene name(s)CAND1
Synonym gene name(s)KIAA0829, TIP120, TIP120A
Protein nameCullin-associated NEDD8-dissociated protein 1
Protein functionKey assembly factor of SCF, SKP1-CUL1-F-box protein E3 ubiquitin ligase complexes that promotes the exchange of the substrate-recognition F-box subunit in SCF complexes, thereby playing a key role in the cellular repertoire of SCF complexes. Acts as a F-box protein exchange factor. The exchange activity of CAND1 is coupled with cycles of neddylation conjugation: in the deneddylated state, cullin-binding CAND1 binds CUL1-RBX1, increasing dissociation of the SCF complex and promoting exchange of the F-box protein. Probably plays a similar role in other cullin-RING E3 ubiquitin ligase complexes. {ECO:0000269|PubMed:12504025, ECO:0000269|PubMed:12504026, ECO:0000269|PubMed:12609982, ECO:0000269|PubMed:16449638, ECO:0000269|PubMed:21249194, ECO:0000269|PubMed:23453757}.
