COP9 Signalosome Complex

A multiprotein complex that functions as a peptide hydrolase, or isopeptidase to cleave NEDD8 PROTEIN from the CULLIN and UBIQUITIN-PROTEIN LIGASES, controlling the activity of the ligases. It is highly conserved in eukaryotes and typically consists of 8 subunits (CSN 1-8 proteins). The COP9 signalosome was originally identified in plants, where it controls gene transcription in response to light.
