Target description
COP9 signalosome complex subunit 5 (UniProt: Q92905; also known as SGN5, Signalosome subunit 5, Jun activation domain-binding protein 1, COPS5) is encoded by the COPS5 (also known as CSN5, JAB1) gene (Gene ID: 10987) in human. COPS5 is the fifth component of the COP9 signalosome (CSN) complex that directly interacts with and regulates the activity of cellular and developmental processes, including checkpoint control, DNA repair, apoptosis, and cell cycle control. This complex is an essential regulator of the ubiquitin conjugation pathway that mediates the deneddylation of the cullin subunits of the SCF-type E3 ligase complexes, leading to a reduction in ubiquitin ligase activity of SCF-type complexes. In the CSN complex, COPS5 probably acts as the catalytic center that mediates the cleavage of Nedd8 from cullins. However, it lacks the metalloproteinase activity and requires the other subunits of CSN complex. COPS5 is present both in the nucleus and cytoplasm. Its nuclear localization is reduced in the presence of interferon induced protein with tetratricopeptide repeats 3 (IFIT3). COPS5 contains a JAMM motif (aa 138-151) that is shown to be essential for the protease activity of the CSN complex. Higher levels of COPS5 are observed in a variety of human cancers and are correlated with a poor prognosis. (Ref.: Kato, J-Y., et al (2006). Hybridoma. 25(6); 342-348).
