产品描述： background: 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. It is involved in macrophage cholesterol and phospholipids transport, and may regulate

cellular lipid homeostasis in other cell types. Six alternative splice variants have been identified.
