C-terminal 14 amino acid residues of rat liver insulin receptor substrate 1.

General description

Insulin receptor substrate 1 (IRS-1) is a 160kD adapter protein which binds to activated insulin receptor and is phosphorylated on multiple tyrosine residues. It plays a crucial role in transmitting signals from the insulin and insulin-like growth factor-1 (IGF-1) receptors to intracellular pathways. Over expression of IRS-1can leads to mammary tumorigenesis and metastasis. Anti-Insulin Receptor Substrate 1 (IRS-1) antibody can be used in western blotting using RIPA lysates of 3T3/A31 mouse fibroblasts. Rabbit anti-Insulin Receptor Substrate 1 (IRS-1) antibody reacts specifically with insulin receptor substrate 1 (165 kD). The product has shown species cross reactivity with rat, mouse and human IRS-1.

Physical form
