Entrez Gene Summary for ACOX1 Gene

  • The protein encoded by this gene is the first enzyme of the fatty acid beta-oxidation pathway, which catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. It donates electrons directly to molecular oxygen, thereby producing hydrogen peroxide. Defects in this gene result in pseudoneonatal adrenoleukodystrophy, a disease that is characterized by accumulation of very long chain fatty acids. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for ACOX1 Gene

ACOX1 (Acyl-CoA Oxidase 1) is a Protein Coding gene. Diseases associated with ACOX1 include Peroxisomal Acyl-Coa Oxidase Deficiency and Mitchell Syndrome. Among its related pathways are Carbon metabolism and Peroxisome. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and protein N-terminus binding. An important paralog of this gene is ACOX2.

UniProtKB/Swiss-Prot Summary for ACOX1 Gene

  • Catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. First enzyme of the fatty acid beta-oxidation pathway.
  • [Isoform 1]: Shows highest activity against medium-chain fatty acyl-CoAs and activity decreases with increasing chain length.
  • [Isoform 2]: Is active against a much broader range of substrates and shows activity towards very long-chain acyl-CoAs. Is twice as active as isoform 1 against 16-hydroxy-palmitoyl-CoA and is 25% more active against 1,16-hexadecanodioyl-CoA.

  • Adrenoleukodystrophy, pseudoneonatal (Pseudo-NALD) [MIM:264470]: A peroxisomal single-enzyme disorder of fatty acid beta-oxidation, resulting in clinical manifestations that remind neonatal adrenoleukodystrophy. Clinical features include mental retardation, leukodystrophy, seizures, mild hepatomegaly, hearing deficit. Pseudo-NALD is characterized by increased plasma levels of very-long chain fatty acids, due to decreased or absent peroxisome acyl-CoA oxidase activity. Peroxisomes are intact and functioning. {ECO:0000269 PubMed:11815777, ECO:0000269 PubMed:17458872, ECO:0000269 PubMed:8040306}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Mitchell syndrome (MITCH) [MIM:618960]: A disorder characterized by episodic demyelination, sensorimotor polyneuropathy, and sensorineural hearing loss. {ECO:0000269 PubMed:32169171}. Note=The gene represented in this entry is involved in disease pathogenesis.
