Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
IRS-1 regulates most insulin responses, including peripheral and central glucose homeostasis, protein synthesis, and cell proliferation and growth. The protein contains an N-terminal pleckstrin homology (PH) domain and phosphotyrosine-binding (PTB) domain which are necessary for targeting IRS-1 to the activated insulin receptor at plasma membrane, where it becomes phosphorylated in response to insulin stimulation of cells. Once phosphorlated by the insulin receptor, the protein binds specifically to various cellular proteins containing Src homology-2 (Sh2) domain, including phosphatidylinositol 3-kinase (PI-3K), Grb2-Sos, and protein tyrosine phosphatase type 11 (PTPN11 or SHP2). In humans, the pathological role of the protein has been detected in non-insulin-dependent diabetes mellitus.
