CC -!- FUNCTION: Catalyzes the transfer of phosphatidylcholine between
CC membranes. Binds a single lipid molecule.
CC -!- SUBUNIT: Interacts with ACOT13/THEM2. {ECO:0000269|PubMed:17704541}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:10500206}.
CC -!- TISSUE SPECIFICITY: Abundant in liver of pups but levels in liver
CC decrease 10-fold about 2 weeks after birth. In adult, highly expressed
CC in epididymis, testis, kidney and bone-marrow derived mast cells.
CC {ECO:0000269|PubMed:10500206}.
