Post Translational Modifications | Constitutive phosphorylation of Ser-262 has no effect on phospholipid transfer activity but is required for Golgi targeting. |
Function | Catalyzes the transfer of phosphatidylinositol and phosphatidylcholine between membranes. Also catalyzes the transfer of sphingomyelin. Required for COPI-mediated retrograde transport from the Golgi to the endoplasmic reticulum.phosphatidylinositol and phosphatidylcholine transfer activity is essential for this function. |
