We find that p110 alpha phosphorylates p85 alpha Ser608 in vivo with significant stoichiometry. However, p110 beta is far less efficient at phosphorylating p85 alpha Ser608, identifying a potential difference in the mechanisms by which these two isoforms are regulated. The p85 alpha Ser608 phosphorylation was increased by treatment with insulin, platelet-derived growth factor, and the phosphatase inhibitor okadaic acid. The functional effects of this phosphorylation are highlighted by mutation of Ser608, which results in reduced lipid kinase activity and reduced association of the p110 alpha catalytic subunit with p85 alpha. |

Here, we demonstrate a requirement for the protein kinase activity of PI(3)K in agonist-dependent beta-adrenergic receptor (betaAR) internalization. Using PI(3)K mutants with either protein or lipid phosphorylation activity, we identify the cytoskeletal protein non-muscle tropomyosin as a substrate of PI(3)K, which is phosphorylated in a wortmannin-sensitive manner on residue Ser 61. A constitutively dephosphorylated (S61A) tropomyosin mutant blocks agonist-dependent betaAR internalization, whereas a tropomyosin mutant that mimics constitutive phosphorylation (S61D) complements the PI(3)K mutant, with only lipid phosphorylation activity reversing the defective betaAR internalization. |

The src homology 2 (sh2) domain of the phosphatidylinositol 3-kinase (pi3k) regulatory subunit binds gab1 in a phosphorylation-independent manner. Moreover, the regulatory subunit of pi3k can mediate the association of gab1 and receptor protein-tyrosine kinases including the insulin, egf, and ngf receptors, all of which phosphorylate gab1. |

In vivo, dominant negative ras mutant n17 inhibits growth factor induced production of 3' phosphorylated phosphoinositides in pc12 cells, and transfection of ras, but not raf, into cos cells results in a large elevation in the level of these lipids. Grb2 binds and activates sos, which then activates ras, and this activates p110 independently of p85. it was also described that ras interacts with pi3k in a direct manner. lysine residue 227 is essential for the interaction of ras with pi3k |

Signal transduction pathways triggered by Tie2 have been extensively examined. Tyr-1101of Tie2 directly associates in a phosphotyrosine (pTyr)-dependent manner with the p85 regulatory subunit of phosphatidylinositol (PI) 3-kinase, which in turn activate PI 3-kinase, leading to cell motility and survival |

We show that pge2 stimulates colon cancer cell growth through its heterotrimeric guanine nucleotide-binding protein (g protein)coupled receptor, ep2, by a signaling route that involves the activation of phosphoinositide 3-kinase and the protein kinase akt by free g protein bg subunits and the direct association of the g protein as subunit with the regulator of g protein signaling (rgs) domain of axin. |

By substituting these tyrosine residues in LAT with phenylalanine and by utilizing phosphorylated peptides derived from these sites, we mapped the tyrosine residues in LAT required for the direct interaction and activation of Vav, p85/p110alpha and phospholipase Cgamma1 (PLCgamma1). Our results indicate that Tyr(226) and Tyr(191) are required for Vav binding, whereas Tyr(171) and Tyr(132) are necessary for association and activation of phosphoinositide 3-kinase activity and PLCgamma1 respectively. |

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 |

Activation of Btk occurs by transphosphorylation of tyrosine 551 in the catalytic domain, resulting in a dramatic increase in the catalytic activity of the kinase (11, 12, 13). This allows for autophosphorylation at tyrosine 223 in the SH3 domain (14). Both Lyn and Syk have been demonstrated to be involved in BCR-mediated Btk activation (11), but processes that drive colocalization of these kinases are ill-defined. Recently, it was suggested that phosphatidylinositol 3-kinase (PI3-K) is also involved in Btk activation |
