Protein
COP9 signalosome complex subunit 5
Organism
Kluyveromyces lactis (strain ATCC 8585 / CBS 2359 / DSM 70799 / NBRC 1267 / NRRL Y-1140 / WM37)
Function
Catalytic Component of the COP9 signalosome (CSN) complex that acts as an regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunit of SCF-type E3 ubiquitin-protein ligase complexes. The CNS complex is involved in the regulation of the mating pheromone response.
Similarity
Belongs to the peptidase M67A family. CSN5 subfamily.
