Description
Phosphatidylinositol transfer protein beta isoform, also known PITPNB, is found in the cytoplasm, where it catalyzes the transfer of phosphatidylinositol (PI) and phosphatidylcholine (PC) between membranes. PITPNB mobilizes PI from the endoplasmic recticulum and regulates the release of PI from stored vesicles in the Golgi network. PITPNB is widely expressed in various tissues
