CC -!- FUNCTION: Component of the COP9 signalosome complex (CSN), a complex
CC involved in various cellular and developmental processes (By
CC similarity). The CSN complex is an essential regulator of the ubiquitin
CC (Ubl) conjugation pathway by mediating the deneddylation of the cullin
CC subunits of SCF-type E3 ligase complexes, leading to decrease the Ubl
CC ligase activity of SCF-type complexes such as SCF, CSA or DDB2 (By
CC similarity). Also involved in the deneddylation of non-cullin subunits
CC such as STON2 (By similarity). The complex is also involved in
CC phosphorylation of p53/TP53, c-jun/JUN, IkappaBalpha/NFKBIA, ITPK1,
CC IRF8/ICSBP and SNAPIN, possibly via its association with CK2 and PKD
CC kinases (By similarity). CSN-dependent phosphorylation of TP53 and JUN
CC promotes and protects degradation by the Ubl system, respectively (By
CC similarity). {ECO:0000250|UniProtKB:Q9BT78}.
CC -!- SUBUNIT: Component of the CSN complex, composed of COPS1/GPS1, COPS2,
CC COPS3, COPS4, COPS5, COPS6, COPS7 (COPS7A or COPS7B), COPS8 and COPS9
CC (By similarity). In the complex, it probably interacts directly with
CC COPS1, COPS2, COPS3, COPS5, COPS6, COPS7 (COPS7A or COPS7B) and COPS8
CC (By similarity). Interacts with TOR1A; the interaction is direct and
CC associates TOR1A and SNAPIN with the CSN complex (By similarity).
CC Interacts with STON2; controls STON2 neddylation levels (By
CC similarity). Interacts with ERCC6 (By similarity).
CC {ECO:0000250|UniProtKB:Q9BT78}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9BT78}. Nucleus
CC {ECO:0000250|UniProtKB:Q9BT78}. Cytoplasmic vesicle, secretory vesicle,
CC synaptic vesicle {ECO:0000250|UniProtKB:Q9BT78}.
CC -!- SIMILARITY: Belongs to the CSN4 family. {ECO:0000305}.
