Prdx1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The PRDX1 gene (Peroxiredoxin 1) encodes a member of the peroxiredoxin family of antioxidant proteins. Peroxiredoxins are crucial for detoxifying reactive oxygen species and regulating cellular redox signaling, making them important in neurodegenerative diseases.

Peroxiredoxin 1 is a ubiquitous antioxidant enzyme:
- Peroxidase activity: Reduces hydrogen peroxide, organic hydroperoxides, and peroxynitrite
- Redox regulation: Uses thioredoxin or glutathione as electron donors
- Chaperone function: Can form high-molecular-weight complexes for protein protection
- Cell signaling: Modulates various signaling pathways through redox regulation
PRDX1 is highly expressed in the brain:
- PRDX1 levels reduced in substantia nigra of PD patients
- Protects dopaminergic neurons from oxidative stress
- Knockout mice show increased vulnerability to MPTP
- Therapeutic target: PRDX1-boosting compounds
- Elevated in early AD (compensatory response)
- Declines with disease progression
- Protects against Aβ-induced oxidative stress
- Potential biomarker: PRDX1 in CSF
- Mutations in PRDX1 rare but associated with disease
- Protects motor neurons from oxidative damage
- Reduced in spinal cord of ALS patients
- Often elevated in cancers (pro-survival)
- Some PRDX1 mutations increase cancer risk
