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. The function of this peroxisomal membrane protein is unknown. However, it is speculated that it may function as a heterodimer for another peroxisomal ABC transporter and, therefore, may modify the adrenoleukodystrophy phenotype. It may also play a role in the process of peroxisome biogenesis. Alternative splicing results in at least two different transcript variants, one which is protein-coding and one which is probably not protein-coding. [provided by RefSeq, Jul 2008]
GeneCards Summary for ABCD4 Gene
ABCD4 (ATP-Binding Cassette, Sub-Family D (ALD), Member 4) is a Protein Coding gene. Diseases associated with ABCD4 include methylmalonic acidemia with homocystinuria, type cblj and cbij. Among its related pathways are Metabolism and Peroxisome. GO annotations related to this gene include ATPase activity and ATPase activity, coupled to transmembrane movement of substances. An important paralog of this gene is ABCD3.
UniProtKB/Swiss-Prot for ABCD4 Gene
May be involved in intracellular processing of vitamin B12 (cobalamin). Could play a role in the lysosomal release of vitamin B12 into the cytoplasm.
