PITPβ Rabbit Polyclonal Antibody

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], function:Catalyzes the transfer of PtdIns and phosphatidylcholine between membranes., PTM:Constitutive phosphorylation of Ser-262 has no effect on phospholipid transfer activity but is required for Golgi targeting., similarity:Belongs to the PtdIns transfer protein family. Class I subfamily., tissue specificity:Widely expressed in various tissues including brain.
