Phosphoinositides are lipids that are present in the cytoplasmic leaflet of a cell's plasma and
internal membranes and play pivotal roles in the regulation of a wide variety of cellular
processes. Phosphoinositides are molecularly diverse due to variable phosphorylation of
the hydroxyl groups of their inositol rings. The rapid and reversible configuration of the
seven known phosphoinositide species is controlled by a battery of phosphoinositide
kinases and phosphoinositide phosphatases, which are thus critical for phosphoinositide …
