[[http://www.uniprot.org/uniprot/SENP2_HUMAN SENP2_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. May down-regulate CTNNB1 levels and thereby modulate the Wnt pathway (By similarity).<ref>PMID:12192048</ref> <ref>PMID:11896061</ref> [[http://www.uniprot.org/uniprot/SUMO2_HUMAN 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.<ref>PMID:9556629</ref> <ref>PMID:18538659</ref> <ref>PMID:18408734</ref>

== Publication Abstract from PubMed ==
 +
The SENP proteases regulate the SUMO conjugates in the cell by cleaving SUMO from target proteins. SENP6 and SENP7 are the most divergent members of the SENP/ULP protease family in humans by the presence of insertions in their catalytic domains. Loop1 insertion is determinant for the SUMO2/3 activity and specificity on SENP6 and SENP7. To gain structural insights into the role of Loop1, we have designed a chimeric SENP2 with the insertion of Loop1 into its sequence. The structure of SENP2-Loop1 in complex with SUMO2 was solved at 2.15 A resolution, and reveals the details of an interface exclusive to SENP6/7 and the formation of unique contacts between both proteins. Interestingly, functional data with SUMO substrates showed an increase of the proteolytic activity in the SENP2-Loop1 chimera for diSUMO2 and polySUMO2 substrates.
