Symbol: csn-5 Name: COP-9 SigNalosome subunit Alias: COP-9 SigNalosome subunit family member (csn-5);WBGENE00000817 Entrez gene ID: 177342 Ensembl gene ID: B0547.1 Species: Worm (Taxid: 6239) Functional description: COP-9 SigNalosome subunit; Probable protease subunit 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 the SCF-type E3 ligase complexes, leading to decrease the Ubl ligase activity of SCF. In the complex, it probably acts as the catalytic center that mediates the cleavage of Nedd8 from cullins. It however has no metalloprotease activity by itself and requires the other subunits of the CSN complex (By similarity). The CSN complex plays an essential role in embryogenesis and oogenesis and is required to regulate microtubule stability in the early embryo. Mediates mei- 3/katanin targeting for degradation at the meiosis to mitosis transition via deneddylation of cul-3.
