Background

SENP1 is a member of the sentrin/SUMO-specific protease (SENP) family. SENP1 localizes to the nucleoplasm and catalyzes the release of SUMO1, SUMO2, and SUMO3 monomers from sumoylated substrates (1,2). SENP1 has been reported to be responsible for intracellular SUMO homeostasis in the control of normal cellular function (2). The removal of sumoylation by SENP1 from many important target proteins, such as HDAC1, HIF-1α, Stat5, p300, Elk-1, and SirT1, leads to the regulation of the related biological pathways (3-8). SENP1-induced desumoylation of HIF-1α stabilizes the target during hypoxia (5), activating downstream VEGF expression and angiogenesis (9). SENP1 desumoylates Stat5 and contributes to Stat5 acetylation and subsequent signaling during normal lymphocyte development (6). Under stress conditions, SENP1 interacts with and inactivates SirT1 by desumoylation, protecting cells from apoptosis (8). SENP1 has been reported to target the progesterone and androgen receptors, either directly or indirectly through HDAC1, thereby upregulating their transcriptional function and potentially affecting receptor-related cancer progression (3,10-13).
