DJ-1 is a multifunctional protein associated with cancers and autosomal early-onset Parkinson disease. Besides the well-documented antioxidative stress activity, recent studies show that DJ-1 has deglycation enzymatic activity and anti-ferroptosis effect. It has been shown that DJ-1 forms the homodi...
