The comprehensive DJ1/PARK7 gene content is maintained at the canonical gene page:
This page provides an in-depth overview of:
- Gene structure and protein: DJ1 encodes a 189-amino-acid protein with a critical cysteine106 residue that serves as an oxidative stress sensor
- Physiological functions: antioxidant defense, mitochondrial homeostasis, transcriptional regulation, DNA repair, protein quality control
- Role in Parkinson's disease: autosomal recessive PD caused by loss-of-function mutations (p.L166P, p.E64D, p.M26I), DJ1 oxidation in sporadic PD, mitochondrial dysfunction
- Therapeutic relevance: DJ1 activators as neuroprotective strategy, mitochondrial protection approaches
- Animal models: DJ1 knockout mice show increased vulnerability to oxidative stress and mitochondrial toxins (MPTP, 6-OHDA)
DJ1 is one of the earliest discovered Parkinson's disease genes (PARK7), identified in 2001 in a Dutch family with autosomal recessive early-onset PD. The canonical gene page at /genes/dj1 contains detailed references and mechanistic information.
