Protein Information (annotations from UniProt)

Database IDHIV0000667
UniProt IDQ9UNS2
Primary gene name(s)COPS3
Synonym gene name(s)CSN3
Protein nameCOP9 signalosome complex subunit 3
Protein functionComponent of the COP9 signalosome complex, CSN, a complex involved in various cellular and developmental processes. The CSN complex is an essential regulator of the ubiquitin, Ubl conjugation pathway by mediating the deneddylation of the cullin subunits of SCF-type E3 ligase complexes, leading to decrease the Ubl ligase activity of SCF-type complexes such as SCF, CSA or DDB2. The complex is also involved in phosphorylation of p53/TP53, c-jun/JUN, IkappaBalpha/NFKBIA, ITPK1 and IRF8/ICSBP, possibly via its association with CK2 and PKD kinases. CSN-dependent phosphorylation of TP53 and JUN promotes and protects degradation by the Ubl system, respectively. {ECO:0000269|PubMed:11285227, ECO:0000269|PubMed:11337588, ECO:0000269|PubMed:12628923, ECO:0000269|PubMed:12732143, ECO:0000269|PubMed:9535219}.
