COPS3 also known as CSN3 or COP9 forms a component of the COP9 signalosome complex. It weighs around 53 kDa. COPS3 is mainly expressed in the cytoplasm of cells in various tissues including the brain heart and skeletal muscle. As part of the signalosome COPS3 plays a role in cellular and molecular processes by influencing protein levels through deneddylation.
Biological function summary
The COPS3/CSN3 protein functions as part of the COP9 signalosome complex which acts in regulating the ubiquitin-proteasome pathway. This complex is involved in mediating the stability and degradation of key regulatory proteins by removing NEDD8 from cullin-RING ligases. By modulating these ligases COPS3 affects protein turnover and signaling pathways essential for cell cycle control and DNA damage response.
Pathways
COPS3/CSN3 takes part in the ubiquitin-proteasome pathway and the DNA damage response pathway. By regulating cullin-RING E3 ubiquitin ligases it influences the degradation of proteins involved in these pathways like p27 and CDT1. Interacting with proteins such as CUL1 and CUL3 COPS3 assists in maintaining cellular homeostasis by ensuring timely protein degradation.
Defects or dysregulation of COPS3 have links to cancer and neurodegenerative diseases. Its role in cancer involves connection to known proteins like p27 where altered protein turnover can lead to unchecked cell proliferation. In neurodegenerative diseases the connection lies with the UPS (ubiquitin-proteasome system) dysfunction affecting protein aggregation processes seen in disorders like Parkinson's disease.
