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         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
