Anti-SUMO2/SUMO3 [8A2] Antibody

This mouse IgG monoclonal antibody was generated against recombinant protein and recognizes SUMO2 and SUMO3 in all vertebrates tested.


  • Reacts with vertebrate SUMO2 and SUMO 3
  • Does not react with SUMO 1
  • Suitable for Immunofluorescence, Immunohistochemistry, Immunoprecipitation and Western Blot applications

Small ubiquitin-related modifiers (SUMOs) are posttranslationally and covalently conjugated to hundreds of other proteins, thereby regulating a wide range of cellular functions, including transcription, DNA replication and repair, nucleocytoplasmic transport, chromosome segregation, mitochondrial fission and ion channel gating. Whereas invertebrates express only one SUMO, vertebrates express three: SUMO1, SUMO2 and SUMO3. SUMO2 and SUMO3 are ~95% identical to each other (and thus often referred to as SUMO2/3), but they are only ~45% identical to SUMO1. SUMO2/3 also more readily form polymeric chains compared to SUMO1, due to the presence of a consensus sumoylation site near their N-termini. These factors suggest that SUMO2/3 may have targets and functions distinct from SUMO1.
