生化机理
COP9 Signalosome Subunit 7A (COPS7A) is a component of the COP9 signalosome complex (CSN), a complex involved in a variety of cellular and developmental processes. The CSN complex is a vital regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunits of SCF-type E3 ligase complexes, thus leading to decrease in the Ubl ligase activity of SCF-type complexes such as SCF, CSA or DDB2. This complex is also involved in phosphorylation of p53/TP53, JUN, I-kappa-B-alpha/NFKBIA, ITPK1 and IRF8/ICSBP, probably through its association with CK2 and PKD kinases. CSN-dependent phosphorylation of TP53 and JUN stimulates and protects degradation by the Ubl system, respectively.
Post-translational: Phosphorylated by CK2 and PKD kinases.

Recombinant Human COPS7A Protein (rp192259) - SDS-PAGE
3 μg/lane of Recombinant Human COPS7A Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 29.0 kDa under reducing conditions and 29.0 & 63.6 kDa under non-reducing conditions.
COPS7A contains a typical coiled-coil structure, formed by repeating heptad sequences (e.g., positions a–g), where the a and d positions are predominantly occupied by hydrophobic residues (such as leucine or isoleucine). These residues mediate hydrophobic interactions to stabilize the interface between helices. This structural motif exhibits a spontaneous tendency to form either homodimers or heterodimers (Uniprot:Q9UBW8).
