11160134	Ly294002 or wortmannin were used to determine whether pi 3-kinasedependent pathways mediate ser307 phosphorylation during insulin/igf-1 or TNF-alpha Stimulation. As expected, the pi-3 kinase inhibitors ly294002 or wortmannin inhibited activation of pkb/akt in insulin or igf-1 stimulated 3t3-l1 preadipocytes, but were without effect on erk1/2. these results suggest that elements of the pi 3-kinase cascade mediate insulin/igf-1stimulated phosphorylation of ser307

17638892	Finally, we report that PTPL1 expression is sufficient to block the IRS-1/phosphatidylinositol 3-kinase/Akt signaling pathway, to inhibit the insulin-like growth factor-I effect on cell survival, and to induce apoptosis.\|We first show by complementary approaches that PTPL1 specifically dephosphorylates insulin receptor substrate-1 (IRS-1) in vitro and in cellulo.

12510059	Insulin also activates jnk, erk, pkc and mtor, which induce the phosphorylation of irs1 on serine residues 307, 612 and 632 and inhibit its functions. Our results indicate that the insulin-stimulated degradation of irs-1 via the phosphatidylinositol 3-kinase pathway is in part dependent upon the ser(312) phosphorylation of irs-1.

17360977	Research has focused on insulin receptor substrate (IRS)-1 as a locus for insulin resistance. Tyrosine phosphorylation of IRS-1 initiates insulin signaling, whereas serine/threonine phosphorylation alters the ability of IRS-1 to transduce the insulin signal. Insulin increased the phosphorylation of Ser312, Ser616, Ser636, Ser892, Ser1101, and Ser1223

Function	May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit (By similarity).
