Phosphatidylinositol-3-phosphate pi3p
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… WebPhosphatidylinositol 3-kinase (PI3K) is an enzyme that phosphorylates phosphatidylinositol (PI) at its 3′-hydroxyl position to produce phosphatidylinositol 3-phosphate (PI3P) . …
