CC -!- FUNCTION: Non-classical phosphatidylinositol (PtdIns) transfer protein
CC (PITP), which exhibits PtdIns-binding/transfer activity in the absence
CC of detectable PtdCho-binding/transfer activity. Regulates PtdIns(4,5)P2
CC homeostasis at the plasma membrane. Heme-binding protein that may play
CC a role in organic oxidant-induced stress responses.
CC {ECO:0000250|UniProtKB:P47008}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol)(in) = a
CC 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol)(out);
CC Xref=Rhea:RHEA:38691, ChEBI:CHEBI:57880;
CC Evidence={ECO:0000250|UniProtKB:P47008};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:38692;
CC Evidence={ECO:0000250|UniProtKB:P47008};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000250|UniProtKB:A6ZQI5};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P47008}.
CC Endoplasmic reticulum membrane {ECO:0000250|UniProtKB:P47008};
CC Peripheral membrane protein {ECO:0000250|UniProtKB:P47008}. Microsome
CC membrane {ECO:0000250|UniProtKB:P47008}; Peripheral membrane protein
CC {ECO:0000250|UniProtKB:P47008}.
CC -!- SIMILARITY: Belongs to the SFH5 family. {ECO:0000305}.
