Phosphatidylinositol transfer protein beta isoform (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 reticulum and regulates its release from stored vesicles in the Golgi network. PITPNB is extensively expressed in various tissues.

PITPNB Human Recombinant fused with a 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 291 amino acids (1-271 a.a.) and having a molecular mass of 33.7kDa. The PITPNB is purified by proprietary chromatographic techniques.

UniProt Protein Function:PITPNB: transfers phosphatidylinositol, phosphatidylcholine and sphingomyelin between membrane bilayers. Associates mainly with the trans-Golgi network. Ser-261 is constitutively phosphorylated.Protein type: Lipid-bindingChromosomal Location of Human Ortholog: 22q12.1Cellular Component: endoplasmic reticulum membrane; Golgi membraneBiological Process: phospholipid transport
UniProt Protein Details:
NCBI Summary: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]
