Essential 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 E3 ligase complexes, leading to modify the Ubl ligase activity. Source: Recombinant full length protein corresponding to aa1-443 of Danio Rerio COP9 Signalosome Complex Subunit 2, fused to 6xHis-Tag at N-terminal, expressed in Yeast.
