CC   -!- FUNCTION: Component of the COP9 signalosome complex (CSN), a complex
CC       involved in various cellular and developmental processes such as
CC       photomorphogenesis and auxin and jasmonate responses. The CSN complex
CC       is an essential regulator of the ubiquitin (Ubl) conjugation pathway by
CC       mediating the deneddylation of the cullin subunits of SCF-type E3
CC       ligase complexes, leading to decrease the Ubl ligase activity of SCF.
CC       It is involved in repression of photomorphogenesis in darkness by
CC       regulating the activity of COP1-containing Ubl ligase complexes (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the CSN complex, probably composed of CSN1, CSN2,
CC       CSN3, CSN4, CSN5 (CSN5A or CSN5B), CSN6 (CSN6A or CSN6B), CSN7 and
CC       CSN8.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus.
CC   -!- SIMILARITY: Belongs to the CSN1 family. {ECO:0000305}.
