NCIt definition : Insulin receptor substrate 1 (1242 aa, 132 kDa) is encoded by the human IRS1 gene.
This protein is involved in insulin-mediated signaling.;
NCIt note : The protein IRS1 acts as an interface between signaling proteins with Src homology-2
domains (SH2 proteins) and the receptors for insulin, IGF2, growth hormone, several
interleukins (IL4, IL9, IL13), and other cytokines. It regulates gene expression and
stimulates mitogenesis and appears to mediate insulin/IGF1-stimulated glucose transport.
