IRS-1 Antibody – Rabbit Polyclonal

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.
