Background InformationSmall ubiquitin-related modifier 2 (UniProt P61956; a.k.a. HSMT3, Sentrin-2, SMT3 homolog 2, Smt3B, SUMO-2, Ubiquitin-like protein SMT3B) and 3 (UniProt P55854; a.k.a. SMT3 homolog 1, Smt3A, SUMO-3, Ubiquitin-like protein SMT3A) are encoded by the SUMO2 (a.k.a. SMT3B, SMT3H2; Gene ID 6613) and SUMO3 (a.k.a. SMT3A, SMT3H1; Gene ID 6612) genes in human. SUMOylation, protein posttranslation modification by small ubiquitin-like modifier (SUMO), is a signaling event in many cellular processes. SUMO proteins are translated as immature precursors and subsequently converted to their mature forms through the activity of sentrin/SUMO-specific proteases (SENPs). As is the case with ubiquitination, SUMOylation is a reversible process. SUMO E1 activating enzyme, E2 conjugating enzyme, and E3 ligase mediate SUMOylation of substrate proteins, while SENPs are responsible for the deSUMOylation. SUMOylation usually occurs at lysine residues in the consensus KxD/E motif, although not all such lysines become SUMOylated and SUMOylation can also occur on lysine residues outside of this motif. SUMO2 and 3 share 97% identity at the amino acid level, while SUMO1 shares approximately 50% and SUMO4 shares about 87% identity with SUMO2/3. SUMO4 is the only SUMO member whose ctivation and conjugation has not been demonstrated. In addition to difference in their target substrates, SUMO2/3 can be SUMOylated and form chains, whereas SUMO1 cannot and may serve as chain terminator.

Key Applications
  • Western Blotting
  • Immunocytochemistry
Application NotesImmunocytochemistry Analysis: Undiluted hybridoma culture supernatant from a representative lot detected SUMO2/3 immunoreactivity in 4% paraformaldehyde-fixed, 0.3% Triton X-100-permeabilized HeLa cells.

Immunocytochemistry Analysis: 10 µg/mL of purified clone 3H12 detected SUMO2/3 immunoreactivity in primary mouse neural progenitor cells (Courtesy of Taro Tachibana, Ph.D., Osaka City University, Japan).

Western Blotting Analysis: 1 µg/mL of purified clone 3H12 detected SUMOylated proteins in HeLa cell lysate (Courtesy of Taro Tachibana, Ph.D., Osaka City University, Japan).

Immunocytochemistry Analysis: A representative lot detected SUMO-2/3 nuclear immunoreactive foci co-localized with those of MCAF1 and SUMO1 and enriched in heterochromatin proteins by indirect immunofluorescent staining of exponentially growing C-33A cells fixed with 4% paraformaldehyde and permeabilized by 0.2% Triton X-100. Trasfecting C-33A cells with SUMO2/3 shRNA or Discosoma sp. red fluorescent protein (DsRed) fusion containg SUMO2/3-interacting sequence (MCAF1 a.a. 965-975) abolished nuclear staining by clone 3H12 (Uchimura, Y., et al. (2006). J. Biol. Chem. 281(32):23180-23190).
