Anti-Insulin Receptor-β: Mouse Insulin Receptor beta Antibody

BACKGROUND Insulin receptor is a transmembrane receptor that is activated by insulin. It belongs to the large class of tyrosine kinase receptors. Two alpha subunits and two beta subunits make up the insulin receptor. The beta subunits pass through the cellular membrane and are linked by disulfide bonds.1 Insulin receptor functions as an enzyme that transfers phosphate groups from ATP to tyrosine residues on intracellular target proteins. Binding of insulin to the alpha subunits causes the beta subunits to phosphorylate themselves (autophosphorylation), thus activating the catalytic activity of the receptor. The activated receptor then phosphorylates a number of intracellular proteins, which in turn alters their activity, thereby generating a biological response.2

Several intracellular proteins have been identified as phosphorylation substrates for the insulin receptor, the best studied of which is insulin receptor substrate 1 or IRS-1. When IRS-1 is activated by phosphorylation, it serves as a type of docking center for recruitment and activation of other enzymes that ultimately mediate insulin's effects, which include activation of PI-3-kinase and MAP kinase pathway etc.3,4
