Sentrin-specific protease 1 (EC 3.4.22.68; UniProt Q9P0U3; also known as Sentrin/SUMO-specific protease SENP1) is encoded by the SENP1 gene (Gene ID 29843) in human. SUMOylation, protein posttranslation modification by small ubiquitin-like modifier (SUMO), is a signaling event in many cellular processes. As is the case with ubiquitination, SUMOylation is a reversible process. SUMO E1 activating enzyme, E2 conjugating enzyme, and E3 ligase mediate SUMOylation of substrate proteins, while a family of SUMO-specific proteases (SENPs) are responsible for the deSUMOylation. Seven SENPs are identified in human (SENP1-3 and SENP5-8). SENP1 processes full-length SUMO1, SUMO2 and SUMO3 to their mature forms and mediates their removal (deconjugation) from substrate proteins, including BHLHE40/DEC1, CCAR2, CLOCK, DBC1, HADC1, HIPK2, MTA1, p53, and SIRT1. SENP1 is reported to be overexpressed and induced by IL-6 in multiple myeloma (MM) cells, and SENP1-knockdown triggers apoptosis and reduces viability, proliferation and colony forming ability of MM cells.
