Rabbit polyclonal to IRS1 ( phospho Y896 )Insulin Receptor Substrate 1 (IRS 1) is a 165 kDa multi-phosphorylated cytoplasmic docking protein involved in the regulation of metabolism and proliferation by insulin, IL-4, and other cytokines. Insulin binding to the insulin receptor activates the catalytic domain and causes phosphorylation on tyrosine residues of IRS proteins, which in turn serve to recruit a variety of Src homology 2 (SH2) domain-containing proteins such as PI3 kinase, Grb 2, SHP 2, Nck and Crk. These proteins further propagate intracellular signalling, culminating in both metabolic and growth-promoting functions of IRS 1. pTyr896 of IRS 1 is a Grb 2 SH2 domain binding site.
