Specificity

Recognizes a protein of 135kDa, identified as the alpha-subunit of insulin receptor (IR). Its epitope localizes in exon 7/8 and shows no cross-reaction with IGF-receptors {Soos, 1986}. Antibody superbly inhibits (>90%) insulin binding and BLOCKS insulin action. IR is a heterotetrameric membrane glycoprotein consisting of disulfide-linked subunits in a beta-a-a-beta configuration. The beta-subunit (95kDa) possesses a single transmembrane domain, whereas the alpha-subunit is completely extracellular. The intracellular portion of the beta-subunit is a tyrosine-specific protein kinase with sequence homology to other such kinases. Activation of kinase is essential in signaling pathway whereby insulin regulates intracellular metabolism.
