ABCD1 is a protein that transfers fatty acids into peroxisomes.


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 is likely involved in the peroxisomal transport or catabolism of very long chain fatty acids.[1]

Clinical significance[edit]

Defects in this gene have been identified as the underlying cause of adrenoleukodystrophy, an X-chromosome recessively inherited demyelinating disorder of the nervous system.[1]

Model organisms[edit]

Model organisms have been used in the study of ABCD1 function. A conditional knockout mouse line, called Abcd1tm1a(EUCOMM)Wtsi[6][7] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[8][9][10]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[4][11] Twenty four tests were carried out on mutant mice but no significant abnormalities were observed.[4]


ABCD1 has been shown to interact with PEX19.[12][13]
