COPS4
This gene encodes one of eight subunits composing COP9 signalosome, a highly conserved protein complex that functions as an important regulator in multiple signaling pathways. The structure and function of COP9 signalosome is similar to that of the 19S regulatory particle of 26S proteasome. COP9 signalosome has been shown to interact with SCF-type E3 ubiquitin ligases and act as a positive regulator of E3 ubiquitin ligases. Two transcript variants encoding different isoforms have been found for this gene.

Interaction
Component of the CSN complex, composed of COPS1/GPS1, COPS2, COPS3, COPS4, COPS5, COPS6, COPS7 (COPS7A or COPS7B), COPS8 and COPS9 isoform 1 (PubMed:18850735, PubMed:26456823). In the complex, it probably interacts directly with COPS1, COPS2, COPS3, COPS5, COPS6, COPS7 (COPS7A or COPS7B) and COPS8 (PubMed:18850735). Interacts with TOR1A; the interaction is direct and associates TOR1A and SNAPIN with the CSN complex (PubMed:21102408). Interacts with STON2; controls STON2 neddylation levels (PubMed:21102408). Interacts with ERCC6 (PubMed:26030138).
