The protein encoded by this gene is a member of the superfamily of
ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and
intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the White subfamily (
subfamily G). It is involved in
macrophage cholesterol and
phospholipids transport, and may regulate cellular lipid
homeostasis in other cell types. Several alternative
splice variants have been identified. == See also ==
