BD, 610109, Purified Mouse Anti-CD220 46/Insulin Receptor Beta

Insulin Receptor (IR) is a transmembrane receptor tyrosine kinase which, upon insulin binding, initiates a cascade of events, including autophosphorylation, phosphorylation of cellular protein substrates, glucose transport, and glycogen synthesis. IR is synthesized as a large glycosylated precursor that is cleaved upon maturation into a 130 kDa α-subunit with kinase activity and a 95 kDa β-subunit. The active Insulin Receptor is a heterotetramer of homologus α and β subunits joined by disulfide bonds. Among the major cytosolic substrates of the Insulin Receptor are IRS-1 and -2, β-Adrenergic receptor, and pp15 (adipocyte lipid-binding protein, ALBP). Autophosphorylation of the IR recruits IRS-1 and -2 to the phosphotyrosines. Subsequently, the phosphorylated IRS-1 and -2 act as docking sites for other signaling proteins like PI3-Kinase, Shc, PTP1D, Nck, etc. In addition, the phosphatase LAR is tightly associated with the IR and LAR becomes activated after insulin stimulation dephosphorylating the IR and its substrates. Therefore, LAR provides a turn-off mechanism in insulin signaling.

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at -20°C.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
