A sub-family of ATP-binding cassette transporters that localize to the membranes of PEROXISOMES; ENDOPLASMIC RETICULUM; and LYSOSOMES. Members contain a transmembrane domain in their N-terminal half and generally function as homodimers in the transport of LIPIDS; BILE ACIDS; and VITAMIN B12. Mutations in some ABCD transporter genes are associated with PEROXISOMAL DISORDERS.
