  • N-terminal region required for both nucleolar localization and interaction with NPM1 in cells
    interspecies homolog to yeast Ulp1p
    ortholog to murine Senp3
  • peptidase C48 family
  • SUMO-specific protease family
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
  • relocating from the nucleoli to the nucleoplasm upon stabilization by ROS, and thus regulating nuclear events
  • sequestrated MDM2 in the nucleolus, and appeared to bind preferentially to MDM2 rather than TP53
  • basic FUNCTION
  • releasing UBL1, SMT3H1 and SMT3H2 monomers from sumoylated substrates
  • acting as a thiol protease
  • might regulate the sumoylation of other substrates through directly binding or mediating association with NPM1 at the nucleolus and other subcellular compartments
  • acting as an essential factor for ribosome biogenesis ,
  • redox sensor that regulates HIF-1 transcriptional activity under oxidative stress through the de-SUMOylation of p300
  • Hsp90/SENP3 association protects SENP3 from STUB1-mediated ubiquitination and subsequent degradation, but this effect of Hsp90 requires the presence of STUB1
  • controls the TP53–MDM2 pathway
  • may play important roles in the pathophysiology of spinal cord injury (SCI)
  • essential for cell proliferation and ribosomal RNA processing
  • might play an important role in the regulation of epithelial ovarian cancer progression
  • might be a novel determinant of multiple pathways governing blood-testis barrier (BTB) dynamics in testis to support germ cells development in mammals
  • CELLULAR PROCESS protein, ubiquitin dependent proteolysis
  • Ubl conjugation pathway
  • SENP3-DLX3 pathway dictates osteogenic differentiation of human stem cells, thus delineating the importance of balanced SUMOylation for epigenetic control of gene expression programs
  • a component
    small molecule
  • UBL1
  • SMT3H1
  • nucleophosmin (NPM1) is an SENP3-binding partner (SENP3-mediated desumoylation might control NPM1 physiological functions at both the nucleolus and other subcellular compartments)
  • specific interaction partner of CDCA8 and catalyzes the removal of SUMO2/3 from CDCA8
  • interacts with STUB1 and Hsp90 in differential modes under non-stress and oxidative stress conditions
  • interacts with TP53 and MDM2, desumoylates both proteins and bound to the acidic domain of MDM2, which also mediates the TP53 interaction, and competed with TP53 for binding
  • PELP1 and the PELP1-associated factor LAS1L are SENP3-sensitive targets of SUMO
  • LAS1L interacts with PELP1, and WDR18, the mammalian homologues of the budding yeast Rix1 complex, along with NOL9 and SENP3, to form a novel nucleolar complex that cofractionates with the 60S preribosomal subunit
  • key target for SENP3-mediated deSUMOylation is the GTPase DNM1L, which plays a major role in regulating mitochondrial fission
  • nutrient-sensing MTOR kinase pathway controls the nucleolar targeting of SENP3 by regulating its interaction with NPM1
  • regulates the global protein turnover and the SP1 level via antagonizing SUMO2/3-targeted ubiquitination and degradation
  • SENP3 could thus enhance STAT3 phosphorylation by de-conjugating the SUMO2/3 modification of STAT3
  • SENP3-mediated deSUMOylation of DNM1L facilitates interaction with MFF to promote cell death
  • MAP2K7, which selectively phosphorylates MAPK8, is a SENP3 substrate and SENP3-mediated deSUMOylation of MAP2K7 may favor its binding to MAPK8
