PtdIns
PtdIns, or phosphatidylinositol, is a class of lipids that are essential components of cell membranes. It is a phospholipid, meaning it contains a phosphate group attached to a glycerol molecule, which is further esterified to two fatty acids. The distinguishing feature of phosphatidylinositol is the inositol sugar molecule that is attached to the phosphate group.
Phosphatidylinositol plays a crucial role in various cellular signaling pathways. It is a precursor for several
Beyond its role in signaling, phosphatidylinositol is also involved in membrane trafficking and protein sorting within
