PRDX2 (Peroxiredoxin 2) is a gene located on chromosome 19p13.13 that encodes a member of the peroxiredoxin family of antioxidant proteins. PRDX2 is a typical 2-Cys peroxiredoxin that reduces hydrogen peroxide, peroxynitrite, and organic hydroperoxides, playing crucial roles in cellular antioxidant defense and redox signaling.
PRDX2 is a cytosolic protein abundant in erythrocytes and most tissues:
PRDX2 is particularly important in neurons, where it provides protection against various oxidative insults.
Parkinson's Disease: PRDX2 is oxidized and inactivated in PD brain. The protein interacts with alpha-synuclein and may influence aggregation.
Alzheimer's Disease: PRDX2 levels are altered in AD brain. The enzyme may protect against amyloid-beta toxicity.
ALS: PRDX2 oxidation has been reported in ALS models and patients.
Stroke: PRDX2 provides neuroprotection against ischemic injury.
The study of Prdx2 — Peroxiredoxin 2 has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
