Tested Applications Positive WB detected in: IGF-1 treated HEK-293T cells Recommended dilution Western Blot (WB): WB : 1:1000-1:4000 Background Information Insulin binding to the insulin receptor (INSR) triggers sequential conformational changes and autophosphorylation of the receptor, followed by activation of a kinase signaling cascade that plays essential roles in a wide variety of biological processes. INSR belongs to a class of receptor tyrosine kinases (RTKs) that comprises 58 receptors in humans. The INSR shares a high structural homology with the IGF1R (84% similarity in the tyrosine kinase domain, 45-65% in the ligand-binding domain, and more than 50% in the overall amino acid sequence). In addition, ligand-dependent activation of the INSR and IGF1R activates almost identical downstream signaling cascades. Insulin binds to INSR in peripheral tissues, initiating receptor activation followed by intracellular signaling cascades. The first step in INSR activation is the autophosphorylation of intracellular tyrosine residues in the JM domain, kinase activation loop, and CT domain. Phosphorylation of three tyrosine residues (Tyr1146, Tyr1150, and Tyr1151, based on INSR isoform A numbering) located in the kinase activation loop plays a crucial role in kinase activity regulation. Insulin binding also induces INSR kinase-mediated phosphorylation of four tyrosine residues located in the JM (Tyr953 and Tyr960) and CT domain (Tyr1316 and Tyr1322).
