X-linked adrenoleukodystrophy (X-ALD), a progressive neurometabolic disorder that is caused by a defect in the gene ABCD1 (ATP-binding cassette, subfamily D, member 1), which encodes the peroxisomal ABC half-transporter ALD protein.
X-linked adrenoleukodystrophy (X-ALD) is caused by mutations in the ABCD1 gene that encodes a peroxisomal membrane located ABC half-transporter named ALDP.
To understand the cell biology and function of mammalian peroxisomal ABC transporters and to determine their role in the pathogenesis of X-ALD we developed a system for expressing functional ABC protein domains in fusion with the maltose binding protein.
X-linked adrenoleukodystrophy (X-ALD) is caused by mutations in the ABCD1 gene, which encodes a peroxisomal ABC half-transporter (ALDP) involved in the import of very long-chain fatty acids (VLCFA) into the peroxisome.
Finally, we discuss variable expression of the peroxisomal ABC proteins and ALDP independent VLCS in relation to the variable clinical presentations of X-ALD.
Adrenoleukodystrophy (ALD) is a demyelinating disease of the central nervous system that results from a genetic deficiency of ALDP, an ABC protein involved in the transport of very long-chain fatty acids (VLCFAs).
A putative gene for ALD was recently identified and surprisingly encodes a protein (ALDP) that belongs to a family of transmembrane transporters regulated or activated by ATP (the ABC proteins).
