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.
Titration of the SUMO-2 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
Purified His-tagged protein was used to produced this monoclonal SUMO-2 antibody.
Aliquot the SUMO-2 antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
