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 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. This peroxisomal membrane protein likely plays an important role in peroxisome biogenesis. Mutations have been associated with some forms of Zellweger syndrome, a heterogeneous group of peroxisome assembly disorders. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]
GeneCards Summary for ABCD3 Gene
ABCD3 (ATP Binding Cassette Subfamily D Member 3) is a Protein Coding gene. Diseases associated with ABCD3 include Bile Acid Synthesis Defect, Congenital, 5 and Zellweger Syndrome. Among its related pathways are Regulation of activated PAK-2p34 by proteasome mediated degradation and Nuclear Receptors in Lipid Metabolism and Toxicity. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and ATPase activity, coupled to transmembrane movement of substances. An important paralog of this gene is ABCD2.
UniProtKB/Swiss-Prot Summary for ABCD3 Gene
Probable transporter involved in the transport of branched-chain fatty acids and C27 bile acids into the peroxisome; the latter function is a crucial step in bile acid biosynthesis (PubMed:25168382). The nucleotide-binding fold acts as an ATP-binding subunit with ATPase activity (PubMed:11248239).
