PIPNB

Phosphatidylinositol transfer protein beta isoform; Isoform 2 of Phosphatidylinositol transfer protein beta isoform; Isoform 3 of Phosphatidylinositol transfer protein beta isoform;Phosphatidylinositol transfer protein beta isoform

Catalyzes the transfer of phosphatidylinositol and phosphatidylcholine between membranes (PubMed:10531358, PubMed:18636990, PubMed:20332109). Also catalyzes the transfer of sphingomyelin (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 (PubMed:20332109).
