===Structure of SENP2-Loop1 in complex with preSUMO-2=== | |||
==Function== | |||
[[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> | |||
