A large, highly conserved, subfamily of ATP binding cassette transporters structurally characterized by a membrane-spanning domain composed of six ALPHA-HELICES, a large extracellular loop, nucleotide-binding domain, and a conserved cytoplasmic 80 amino acid sequence. In humans, it includes ABCA1(ATP BINDING CASSETTE TRANSPORTER 1) through ABCA10, as well as ABCA12 and ABCA13.
