The COPS7B Polyclonal Antibody (PAC04118) is a valuable tool for researchers studying COPS7B, a subunit of the COP9 signalosome complex involved in regulating protein degradation. This antibody, produced in rabbits, shows high specificity and reactivity with human samples, making it ideal for use in Western blot applications. By targeting the COPS7B protein, this antibody enables precise detection and analysis in various cell types, facilitating research in cell biology, protein degradation pathways, and cancer biology.
COPS7B plays a crucial role in the assembly and function of the COP9 signalosome complex, which regulates the degradation of key proteins involved in cell cycle control, signal transduction, and DNA repair. Dysregulation of COPS7B has been implicated in various diseases, including cancer, making it a promising target for therapeutic interventions. Understanding the function and regulation of COPS7B is essential for unraveling its role in disease progression and identifying potential treatment strategies.

Background:
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, JUN, I-kappa-B-alpha/NFKBIA, ITPK1 and IRF8/ICSBP, 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.
