SUMO2 is a ubiquitin-like protein which can be covalently attached to target lysines either as a monomer or as a lysine-linked polymer. SUMO2 does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process. This protein plays a role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Covalent attachment to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by E3 ligases such as PIAS isoforms 1-4.
Suitable for use in ELISA, Western Blot and mmunohistochemistry. Other applications not tested.
Western Blot: 1-2ug/ml
Immunohistochemistry (Formalin fixed paraffin embedded): 5ug/ml
Optimal dilutions to be determined by the researcher.
Storage and Stability:
