FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the insulin receptor substrate 2, a cytoplasmic signaling molecule that mediates effects of insulin, insulin-like growth factor 1, and other cytokines by acting as a molecular adaptor between diverse receptor tyrosine kinases and downstream effectors. The product of this gene is phosphorylated by the insulin receptor tyrosine kinase upon receptor stimulation, as well as by an interleukin 4 receptor-associated kinase in response to IL4 treatment.

PHENOTYPE: Homozygous disruption of this gene results in type 2 diabetes due to insulin resistance and pancreatic beta cell dysfunction, causes defects in leptin action, energy balance, lipid homeostasis and vascular wound healing, and leads to female infertility due to hypothalamic and ovarian dysfunction.
