p-Insulin Receptor (Y1355) polyclonal antibody detects endogenous levels of Insulin Receptor protein only when phosphorylated at Tyr1355.
The insulin receptor (IR) is a heterodimeric protein complex that has an intracellular ? subunit and an extracellular ? subunit, which is disulfide- linked to a transmembrane segment. The insulin ligand binds to the IR and initiates molecular signaling pathways that promote glucose uptake in cells and glycogen synthesis. Insulin binding to IR induces phosphorylation of intracellular tyrosine kinase domains and recruitment of multiple SH2 and SH3 domain-containing intracellular proteins that serve as signaling intermediates for pleiotropic effects of insulin.
