What is
abca1
The membrane-associated 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
intracellular membranes. ABC genes are divided into seven distinct
subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This
protein is a member of the ABC1 subfamily. Members of the ABC1
subfamily comprise the only major ABC subfamily found exclusively
in multicellular eukaryotes. In humans, this protein functions as a
cholesterol efflux pump in the cellular lipid removal pathway.
Mutations in the human gene have been associated with Tangiers
disease and familial high-density lipoprotein deficiency.
