Dynamics of Lipid Transfer by Phosphatidylinositol Transfer Proteins in Cells

Of many lipid transfer proteins identified, all have been implicated in essential cellular processes, but the activity of none has been demonstrated in intact cells. Among these, phosphatidylinositol transfer proteins (PITP) are of particular interest as they can bind to and transfer phosphatidylinositol (PtdIns)--the precursor of important signalling… CONTINUE READING
