General description

Insulin receptor substrate 1 (IRS1) gene is mapped to human chromosome 2q36.3. The gene encodes a 185 kDa protein and is ubiquitously expressed. Irs1 belongs to the group of cytoplasmic adaptor proteins.

Immunogen

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

Application

Anti-Insulin Receptor Substrate 1 (IRS-1) antibody can be used in immunoprecipitation using 0.5 mg of a 3T3/A31 RIPA lysate.

Biochem/physiol Actions

Insulin receptor substrate 1 (IRS-1) 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

Solution in 0.1 M Tris-glycine, pH 7.4, containing 0.15 M NaCl, and 0.05% sodium azide.

The insulin and insulin-like growth factor-I (IGF-I) receptors are tyrosine kinases. Consequently, an approach to investigating signaling pathways from these receptors is to characterize proteins rapidly phosphorylated on tyrosine in response to insulin and IGF-I. In many cell types the
