Introduction
Aox1 Aldehyde Oxidase 1 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [@terao2023]
Gene Overview
Function
AOX1 encodes aldehyde oxidase, a homodimeric enzyme that catalyzes the oxidation of aldehydes into carboxylic acids. This enzyme is part of the molybdenum hydroxylase family and requires molybdenum, FAD, and iron-sulfur clusters for its activity.

Gene Overview
Function
AOX1 encodes aldehyde oxidase, a homodimeric enzyme that catalyzes the oxidation of aldehydes into carboxylic acids. This enzyme is part of the molybdenum hydroxylase family and requires molybdenum, FAD, and iron-sulfur clusters for its activity.
Key Functions
Drug Metabolism: Aldehyde oxidase is involved in the metabolism of xenobiotics, including drugs and environmental compounds
Retinal Metabolism: Plays a role in the visual cycle by metabolizing retinaldehyde
[Reactive Oxygen Species](/entities/reactive-oxygen-species) Generation: Produces hydrogen peroxide during aldehyde oxidation, contributing to oxidative stress
Disease Associations
Alzheimer's Disease
AOX1 expression and activity are altered in Alzheimer's disease brains. The enzyme may contribute to [amyloid-beta](/proteins/amyloid-beta) oxidation and neuroinflammation through its production of reactive oxygen species.
Parkinson's Disease
Aldehyde oxidase may play a role in PD through:
Metabolism of dopamine oxidation products
Generation of oxidative stress
Possible interaction with neuromelanin
Amyotrophic Lateral Sclerosis (ALS)
AOX1 is expressed in motor [neurons](/entities/neurons) and may contribute to oxidative stress in ALS. Altered aldehyde oxidase activity has been reported in ALS patients.
Neurodegeneration
The enzyme's role in oxidative stress makes it relevant to various neurodegenerative conditions:
Generates hydrogen peroxide during catalysis
Can produce reactive aldehydes that form protein adducts
May interact with metal homeostasis (molybdenum cofactor)
Expression
AOX1 is expressed in various tissues:
Liver (highest expression)
Lung
Kidney
Brain (lower expression)
In the brain, expression is observed in:
[Cortex](/brain-regions/cortex)
[Hippocampus](/brain-regions/hippocampus)
Basal ganglia
