LMP000472

Record overview

LMPD IDLMP000472
Gene ID23760
SpeciesHomo sapiens (Human)
Gene Namephosphatidylinositol transfer protein, beta
Gene SymbolPITPNB
SynonymsPI-TP-beta; PtdInsTP; VIB1B
Alternate namesphosphatidylinositol transfer protein beta isoform; PtdIns transfer protein beta; phosphotidylinositol transfer protein, beta
Chromosome22
Map Location22q12.1
SummaryThis 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]
