General Information
Term phosphatidylserine-phosphatidylinositol-4-phosphate exchange activity ID (Ontology) GO:0160270 (Gene Ontology)
Definition Catalysis of the reaction: a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol 4-phosphate)(out) + a 1,2-diacyl-sn-glycero-3-phospho-L-serine(in) = a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol 4-phosphate)(in) + a 1,2-diacyl-sn-glycero-3-phospho-L-serine(out). This reaction results in the exchange of phosphatidylserine (PS) for phosphatidylinositol-4-phosphate (PI(4)P) between membranes.[ PubMed:34249917 PubMed:39106189 ]
