ACOX1/AOX

Function

Involved in the initial and rate-limiting step of peroxisomal beta-oxidation of straight-chain saturated and unsaturated very-long-chain fatty acids (PubMed:15060085, PubMed:17458872, PubMed:17603022, PubMed:32169171, PubMed:33234382, PubMed:7876265). Catalyzes the desaturation of fatty acyl-CoAs such as palmitoyl-CoA (hexadecanoyl-CoA) to 2-trans-enoyl-CoAs ((2E)-enoyl-CoAs) such as (2E)-hexadecenoyl-CoA, and donates electrons directly to molecular oxygen (O(2)), thereby producing hydrogen peroxide (H(2)O(2)) (PubMed:17458872, PubMed:17603022, PubMed:7876265).

Isoform 1

Shows highest activity against medium-chain fatty acyl-CoAs. Shows optimum activity with a chain length of 10 carbons (decanoyl-CoA) in vitro.

Isoform 2

Is active against a much broader range of substrates and shows activity towards long-chain fatty acyl-CoAs.

Involvement in disease

Adrenoleukodystrophy, pseudoneonatal

Pseudo-NALD

A peroxisomal single-enzyme disorder of fatty acid beta-oxidation, resulting in clinical manifestations that remind neonatal adrenoleukodystrophy. Clinical features include intellectual disability, 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.

None

The disease is caused by variants affecting the gene represented in this entry.

Mitchell syndrome

MITCH

A disorder characterized by episodic demyelination, sensorimotor polyneuropathy, and sensorineural hearing loss.

None

The gene represented in this entry is involved in disease pathogenesis.

Pathway

Lipid metabolism; peroxisomal fatty acid beta-oxidation.

Sequence similarities

Belongs to the acyl-CoA oxidase family.

Tissue specificity

Widely expressed with highest levels of isoform 1 and isoform 2 detected in testis. Isoform 1 is expressed at higher levels than isoform 2 in liver and kidney while isoform 2 levels are higher in brain, lung, muscle, white adipose tissue and testis. Levels are almost equal in heart.
