Functioni

Component 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, 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. Has some glucocorticoid receptor-responsive activity (By similarity). Stabilizes RFWD2/COP1 through reducing RFWD2 auto-ubiquitination and decelerating RFWD2 turnover rate, hence regulates the ubiquitination of RFWD2 targets, including SFN (By similarity).By similarity

Interactioni

Subunit structurei

Component of the CSN complex, composed of COPS1/GPS1, COPS2, COPS3, COPS4, COPS5, COPS6, COPS7 (COPS7A or COPS7B) and COPS8. In the complex, it probably interacts directly with COPS2, COPS4, COPS5 and COPS7 (COPS7A or COPS7B). Interacts with the translation initiation factor EIF3S6. Interacts weakly with RBX1 (By similarity). Directly interacts with RFWD2 and 14-3-3 protein sigma/SFN (By similarity).By similarity

Caution

Although related to the peptidase M67A family, it lacks the JAMM motif that probably constitutes the catalytic center and therefore it probably does not have a protease activity.Curated
