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, Palmitoyl) is a Protein Coding gene. Diseases associated with ACOX1 include peroxisomal acyl-coa oxidase deficiency and anoxia. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include receptor binding and flavin adenine dinucleotide binding. An important paralog of this gene is ACOX3.

UniProtKB/Swiss-Prot for ACOX1 Gene

  • Catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. 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. Isoform 2 is twice as active as isoform 1 against 16-hydroxy-palmitoyl-CoA and is 25% more active against 1,16-hexadecanodioyl-CoA.

    • Isoform 1 and isoform 2 can reverse the Acox1 null phenotype in mouse which is characterized by severe microvesicular hepatic steatosis, sustained activation of Ppara, spontaneous massive peroxisome proliferation and eventual development of hepatocellular carcinomas. Isoform 2 is more effective in reversal of the phenotype than isoform 1 (PubMed:20195242).

  • 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}.
