PITPNM3

Nir1 or membrane-associated phosphatidylinositol transfer protein 3 (PITPNM3) is a mammalian protein that localizes to endoplasmic reticulum (ER) and plasma membrane (PM) membrane contact sites (MCS) and aids the transfer of phosphatidylinositol between these two membranes, potentially by recruiting additional proteins to the ER-PM MCS. It is encoded by the gene PITPNM3.
