The mammalian phospholipid exchange protein PITPalpha (phosphatidylinositol transfer protein alpha), found in both extranuclear and endonuclear compartments, is thought in part to facilitate nuclear import of the PtdIns (phosphatidylinositol) consumed in the generation of proliferation-associated endonuclear diacylglycerol accumulations. Unlike phosphatidylcholine, endonuclear PtdIns is not synthesized in situ. However, despite progressive postnatal lethality of PITPalpha ablation in mice… CONTINUE READING
