Function

[SENP1_HUMAN] Protease that catalyzes two essential functions in the SUMO pathway: processing of full-length SUMO1, SUMO2 and SUMO3 to their mature forms and deconjugation of SUMO1, SUMO2 and SUMO3 from targeted proteins. Deconjugates SUMO1 from HIPK2. Deconjugates SUMO1 from HDAC1, which decreases its transcriptional repression activity.^[1] ^[2] ^[3] ^[4] [SUMO2_HUMAN] Ubiquitin-like protein that can be covalently attached to proteins as a monomer or as a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by an E3 ligase such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Polymeric SUMO2 chains are also susceptible to polyubiquitination which functions as a signal for proteasomal degradation of modified proteins.^[5] ^[6] ^[7]

Publication Abstract from PubMed

The SUMO (small ubiquitin-like modifier)-specific protease SENP1 (sentrin-specific protease 1) can process the three forms of SUMO to their mature forms and deconjugate SUMO from modified substrates. It has been demonstrated previously that SENP1 processed SUMO-1 more efficiently than SUMO-2, but displayed little difference in its ability to deconjugate the different SUMO paralogues from modified substrates. To determine the basis for this substrate specificity, we have determined the crystal structure of SENP1 in isolation and in a transition-state complex with SUMO-2. The interface between SUMO-2 and SENP1 has a relatively poor complementarity, and most of the recognition is determined by interaction between the conserved C-terminus of SUMO-2 and the cleft in the protease. Although SENP1 is rather similar in structure to the related protease SENP2, these proteases have different SUMO-processing activities. Electrostatic analysis of SENP1 in the region where the C-terminal peptide, removed during maturation, would project indicates that it is the electrostatic complementarity between this region of SENP1 and the C-terminal peptides of the various SUMO paralogues that mediates selectivity.

The structure of SENP1-SUMO-2 complex suggests a structural basis for discrimination between SUMO paralogues during processing.,Shen LN, Dong C, Liu H, Naismith JH, Hay RT Biochem J. 2006 Jul 15;397(2):279-88. PMID:16553580^[8]
