UniProtKB accession:  P53812

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the transfer of phosphatidylinositol between membranes (PubMed:18636990). Also catalyzes the transfer of phosphatidylcholine and sphingomyelin between membranes (By similarity). Required for COPI-mediated retrograde transport from the Golgi to the endoplasmic reticulum; phosphatidylinositol and phosphatidylcholine transfer activity is essential for this function (By similarity).
