FUNCTION
Insulin receptor substrate 1 plays a key role in transmitting signals from the insulin and insulin-like growth factor-1 (IGF-1) receptors to intracellular pathways PI3K / Akt and Erk MAP kinase pathways. Tyrosine phosphorylation of IRS-1 by insulin receptor (IR) introduces multiple binding sites for proteins bearing SH2 homology domain, such as PI3K, Grb-2/Sos complex and SHP2. PI3K, involved in interaction with IRS-1, produces PIP3, which, in turn, recruits Akt kinase. Further, Akt kinase is activated via phosphorylation of its T308 residue and analogous sites in PKC by PDK1. This phosphorylation is absent in tissues lacking IRS-1. The cascade is followed by glucose uptake. Formation of the Grb-2/Sos complex, also known as the RAS guanine nucleotide exchange factor complex, results in ERK1/2 activation. IRS-1 signal transduction may be inhibited by SHP2 in some tissues.
