Anti-Swine H1N1 Hemagglutinin

Anti-Swine H1N1 Hemagglutinin Antibody was affinity purified from monospecific antiserum by immunoaffinity chromatography. Cross reactivity with Swine H1N1 Hemagglutinin from other sources has not been determined. Protein function: 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. [The UniProt Consortium]
