Previous GeneCards Identifiers for COPS7A Gene
This gene encodes a component of the COP9 signalosome, an evolutionarily conserved multi-subunit protease that regulates the activity of the ubiquitin conjugation pathway. Alternatively spliced transcript variants that encode the same protein have been described. [provided by RefSeq, Mar 2014]
GeneCards Summary for COPS7A Gene
COPS7A (COP9 Signalosome Subunit 7A) is a Protein Coding gene. Among its related pathways are Vesicle-mediated transport and Transcription-Coupled Nucleotide Excision Repair (TC-NER). An important paralog of this gene is COPS7B.
UniProtKB/Swiss-Prot for COPS7A 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, 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.
