Abstract Phosphatidylinositol 3-kinase (PI 3-kinase) has been implicated as a participant in
signaling pathways regulating cell growth by virtue of its activation in response to various …

Abstract Phosphatidylinositol (PI) 3-kinase is a heterodimer consisting of an 85-kDa subunit
(p85) and 110-kDa subunit (p110). The 85-kDa noncatalytic subunit, which contains two Src …

Abstract Phosphatidylinositol (PI) 3-kinase is a heterodimeric enzyme comprising a 110-kDa
catalytic subunit and an 85-kDa regulatory subunit that binds to tyrosine phosphopeptide …

Previous studies have suggested that the two subunits of phosphatidylinositol (PI) 3-kinase,
p85 and p110, function as localizing and catalytic subunits, respectively. Using recombinant …

A phosphatidylinositol (PI) 4-kinase cDNA was cloned from a rat brain cDNA library. This
cDNA encoded a protein of 2041 amino acids with a calculated molecular weight of …

Phosphatidylinositol 3-kinase (PI 3-kinase) is stimulated by association with a variety of
tyrosine kinase receptors and intracellular tyrosine-phosphorylated substrates. We isolated …

Phosphatidylinositol 3-kinase, which is composed of a 110-kDa catalytic subunit and a
regulatory subunit, plays important roles in various cellular signaling mechanisms. We …

Phosphatidylinositol (PI) 3-kinase is a cytoplasmic signaling molecule recruited to the
membrane by activated growth factor receptors. The p85 subunit of PI 3-kinase links the …

Phosphatidylinositol (PI) 3-kinases catalyze the formation of 3′-phosphoinositides, which
appear to promote cellular responses to growth factors and such membrane trafficking …

Phosphatidylinositol (PI) 3‐kinase has an 85 kDa subunit (p85 alpha) which mediates its
association with activated protein tyrosine kinase receptors through SH2 domains, and an …
