COP9 Signalosome Complex Subunit 1

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** COP9 signalosome complex subunit 1 (491 aa, ~56 kDa) is encoded by the human GPS1 gene. This protein plays a role in the regulation of the ubiquitin (Ubl) conjugation pathway and the suppression of G-protein and mitogen-activated protein kinase-mediated signal transduction.
