This gene encodes a cytoplasmic protein that catalyzes the transfer of phosphatidylinositol and phosphatidylcholine between membranes. This transfer activity is required for COPI complex-mediated retrograde transport from the Golgi apparatus to the endoplasmic reticulum. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Sep 2013]
PITPNB (Phosphatidylinositol Transfer Protein Beta) is a Protein Coding gene. Diseases associated with PITPNB include Cleft Soft Palate and Cerebellopontine Angle Tumor. Among its related pathways are PI Metabolism and Glycerophospholipid biosynthesis. Gene Ontology (GO) annotations related to this gene include lipid binding. An important paralog of this gene is PITPNA.
