ABCD3 a member of the superfamily of ATP-binding cassette (ABC) transporters. Likely plays an important role in peroxisome biogenesis. 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 ALD subfamily, which is involved in peroxisomal import of fatty acids and/or fatty acyl-CoAs in the organelle. All known peroxisomal ABC transporters are half transporters which require a partner half transporter molecule to form a functional homodimeric or heterodimeric transporter. Defects in ABCD3 may be the cause of Zellweger syndrome-2 (ZWS-2), an autosomal recessive disorder due to defective import mechanisms for peroxisomal matrix enzymes.
