IRS1 (mouse)

Overview
IRS1 an adaptor protein that is one of the major substrates of the insulin receptor kinase. Contains multiple tyrosine phosphorylation motifs that serve as docking sites for SH2-domain-containing proteins including phosphatidylinositol 3-kinase p85 subunit and GRB-2. Phosphorylated on ser/thr residues by kinases including JNK and IKK. Note: This description may include information from UniProtKB.
