SENPs are a group of cysteine-type peptidases that catalyze two essential functions in the SUMO pathways: processing of full-length small Ubiquitin-related modifiers (SUMOs) to their mature forms and deconjugation of SUMOs from SUMOylated proteins. SENP2 is 589 amino acids (aa) in length with a predicted molecular weight of 67.9 kDa. Human SENP2 shares 88% and 87% aa sequence identity with the mouse and rat orthologs, respectively. Mammalian SENPs share a conserved C-terminal catalytic domain while the N-terminal domains have no significant similarity. The N-terminal domain of SENP2 contains a nuclear localization signal and a CRM1-dependent nuclear export signal allowing SENP2 to shuttle between the nucleus and cytoplasm. In the nucleus, SENP2 associates with Nup153, a nucleoporin that is located on the nucleoplasmic side of the nuclear pore complex. It is thought that SENP2 functions are regulated by its association with the nuclear pore complex and nucleocytoplasmic shuttling. SENP2 has been shown to deSUMOylate multiple proteins including C/EBP beta, ROR alpha/NR1F1, IRF3, MEF2A, and NEMO. Consequently, SENP2 is thought to be critical for the regulation of various cellular processes such as adipogenesis, immune responses, and cancer cell growth. Additionally, SENP2 deSUMOylates MDM2, allowing MDM2 to bind and ubiquitinate p53. SENP2-mediated regulation of MDM2 appears to be critical for the development of the trophoblast during embryogenesis and maintenance of the genome during stress responses.
