The PI3K is activated by G protein-coupled receptors and tyrosine kinase receptors. (wikipedia.org)
They associate with a regulatory subunit of the p85 family and are activated by tyrosine kinase receptors. (umbc.edu)
Protein kinases2
The PI3K catalytic domain family is part of a larger superfamily that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and RIO kinases. (umbc.edu)
Phosphoinositide 3-kinases (PI3Ks), also called phosphatidylinositol 3-kinases, are a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. (wikipedia.org)
The discovery of PI3Ks by Lewis Cantley and colleagues began with their identification of a previously unknown phosphoinositide kinase associated with the polyoma middle T protein. (wikipedia.org)
They observed unique substrate specificity and chromatographic properties of the products of the lipid kinase, leading to the discovery that this phosphoinositide kinase had the unprecedented ability to phosphorylate phosphoinositides on the 3' position of the inositol ring. (wikipedia.org)
Subsequently, Cantley and colleagues demonstrated that in vivo the enzyme prefers PtdIns(4,5)P2 as a substrate, producing the novel phosphoinositide PtdIns(3,4,5)P3 previously identified in neutrophils. (wikipedia.org)

PI3K5
The PI3K family is divided into four different classes: Class I, Class II, Class III, and Class IV. (wikipedia.org)
In regular cells, PI(3,4,5)P3 can be briefly induced by development element excitement and it is metabolized by lipid phosphatases quickly, including phosphatase and tensin homolog (PTEN), terminating PI3K signaling by detatching the 3 phosphoric acidity from PI(3,4,5)P3. (portefeuillessac.com)

P1103
Class IA PI3Ks are composed of a heterodimer between a p110 catalytic subunit and a shorter regulatory subunit (often p85). (wikipedia.org)
The regulatory p101 and catalytic p110γ subunits comprise the class IB PI3Ks and are encoded by a single gene each (Pik3cg for p110γ and Pik3r5 for p101). (wikipedia.org)
Class I PI3Ks are heterodimers consisting of a p110 catalytic subunit and a regulatory subunit of either the p85 type (associated with the class IA p110 isoforms p110α, p110β or p110delta) or the p101 type (associated with the class IB p110 isoform p110γ). (expasy.org)
Heterodimers2
Class III PI3Ks produce only PI(3)P from PI but are more similar to Class I in structure, as they exist as heterodimers of a catalytic (Vps34) and a regulatory (Vps15/p150) subunits. (wikipedia.org)
Class I enzymes are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (out of four isoforms) and one of several regulatory subunits. (umbc.edu)
Lipid1
Phosphatidylinositol 3-kinases (PI3Ks) are lipid kinases that phosphorylate 4,5-bisphonate (PI(4,5) P2 or PIP2) at the 3-position of the inositol ring, and thus generate phosphatidylinositol 3,4,5-trisphosphate (PIP3), which, in turns, initiates a vast array of signaling events. (expasy.org)
