NCIt related terms : PI3K; PI3 kinase; phosphatidylinositol-3 kinase;
NCIt definition : An enzyme that catalyzes the conversion of phosphatidylinositol to phosphatidylinositol
3-phosphate. This is the first committed step in the biosynthesis of phosphatidylinositol
3,4-bisphosphate and phosphatidylinositol 3,4,5-trisphosphate. This pathway is thought
to play a critical role in DNA repair, V(D)J recombination and cell cycle checkpoints.
(from LocusLink);
Alternative definition : NCI-GLOSS: A type of enzyme that transmits signals in cells and that helps control
cell growth. Some tumors have higher-than-normal levels of phosphatidylinositol-3
kinase.;
