CC   -!- FUNCTION: Component of the COP9 signalosome complex (CSN), a complex
CC       involved in various cellular and developmental processes. The CSN
CC       complex is an essential regulator of the ubiquitin (Ubl) conjugation
CC       pathway by mediating the deneddylation of the cullin subunits of SCF-
CC       type E3 ligase complexes, leading to decrease the Ubl ligase activity
CC       of SCF-type complexes such as SCF, CSA or DDB2. The complex is also
CC       involved in phosphorylation of p53/TP53, c-jun/JUN,
CC       IkappaBalpha/NFKBIA, ITPK1 and IRF8/ICSBP, possibly via its association
CC       with CK2 and PKD kinases. CSN-dependent phosphorylation of TP53 and JUN
CC       promotes and protects degradation by the Ubl system, respectively (By
CC       similarity). {ECO:0000250}.
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       In the complex, it probably interacts directly with COPS3, COPS4 and
CC       COPS7 (COPS7A or COPS7B). {ECO:0000250|UniProtKB:Q99627}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CSN8 family. {ECO:0000305}.
