Phosphatidylinositol 3-phosphate (PtdIns3P) is a phospholipid found in cell membranes that helps to recruit a range of proteins, many of which are involved in protein trafficking, to the membranes. It is the product of both the class II and III phosphoinositide 3-kinases (PI 3-kinases) activity on phosphatidylinositol. PtdIns3P is dephosphorylated by the myotubularin family of phosphatases, on the D3 position of t… WebNomenclature. Phosphatidylinositol (PI) is the initial substrate for a number of phosphoinositide kinases that phosphorylate the hydroxyl groups along the inositol ring. …

Phosphatidylinositol 3,5-bisphosphate [PtdIns(3,5)P 2] is an important lipid in membrane trafficking in animal and yeast systems; however, its role is still largely obscure in plants.Here, we demonstrate that the phosphatidylinositol 3-phosphate 5-kinase, formation of aploid and binucleate cells1 (FAB1)/FYVE finger-containing phosphoinositide kinase …
WebPhosphatidylinositol 3-kinases (PtdIns 3-kinases) that produce phosphatidylinositol (3,4,5) triphosphate (PtdIns(3,4,5)P(3)) are considered to be important regulators of actin dynamics in animal cells. In plants, neither PtdIns(3,4,5)P(3) nor the enzyme that produces this lipid has been reported.
