PITPNB: Lysates

PITPNB, also known as Phosphatidylinositol Transfer Protein Beta, has two isoforms that are each approximately 32 kDa with 271 and 272 amino acids, respectively. PITPNB is localized to the cytoplasm and expressed in a variety of tissues, including the brain. PITPNB is responsible for catalyzing the transfer of phosphatidylcholine and phosphatidylinositol between membranes. Pathways in which PITPNB plays a role include phospholipid metabolism and PI/PC transport between the ER and Golgi membranes. Current research on PITPNB is being conducted in relation to obesity, and PITPNB has been shown to interact with Von Hippel Lindau, Ubiquitin C, Lamin A and LMO4.
