Previous GeneCards Identifiers for COPS3 Gene
The protein encoded by this gene possesses kinase activity that phosphorylates regulators involved in signal transduction. It phosphorylates I kappa-Balpha, p105, and c-Jun. It acts as a docking site for complex-mediated phosphorylation. The gene is located within the Smith-Magenis syndrome region on chromosome 17. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]
GeneCards Summary for COPS3 Gene
COPS3 (COP9 Signalosome Subunit 3) is a Protein Coding gene. Diseases associated with COPS3 include Smith-Magenis Syndrome and Bone Angioendothelial Sarcoma. Among its related pathways are Transcription-Coupled Nucleotide Excision Repair (TC-NER) and Vesicle-mediated transport. An important paralog of this gene is PSMD3.
UniProtKB/Swiss-Prot Summary for COPS3 Gene
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, c-jun/JUN, IkappaBalpha/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.
