DESCRIPTION

Also known as ABCD3_HUMAN, ABCD3, PMP70, PXMP1. Broad substrate specificity ATP-dependent transporter of the ATP-binding cassette (ABC) family that catalyzes the transport of long-chain fatty acids (LCFA)-CoA, dicarboxylic acids-CoA, long-branched-chain fatty acids-CoA and bile acids from the cytosol to the peroxisome lumen for beta-oxydation (PubMed:11248239, PubMed:25168382, PubMed:24333844, PubMed:29397936). Has fatty acyl-CoA thioesterase and ATPase activities (PubMed:29397936). Probably hydrolyzes fatty acyl-CoAs into free fatty acids prior to their ATP-dependent transport into peroxisomes (By similarity). Thus, play a role in regulation of LCFAs and energy metabolism namely, in the degradation and biosynthesis of fatty acids by beta-oxidation (PubMed:25944712, PubMed:24333844). Homodimers (PubMed:17609205). Can forms heterodimers with ABCD1 and ABCD2 (PubMed:10777694, PubMed:10551832, PubMed:17609205). Dimerization is necessary to form an active transporter (PubMed:17609205). Interacts with PEX19; mediates the targeting of ABCD3 to peroxisomes (PubMed:10704444, PubMed:16344115, PubMed:17761678).
