General description

Protein DJ-1 (UniProt Q99497; also known as Parkinson disease (autosomal recessive, early onset) protein 7, Epididymis secretory sperm binding protein Li 67p, Oncogene DJ1) is encoded by the PARK7 (also known as DJ1, HEL-S-67p) gene (Gene ID 11315) in human. DJ-1 belongs to the ThiJ/PfpI family of proteins characterized by a ThiJ domain. DJ-1 is reported to be involved in multiple physiological processes, including cellular oncogenic transformation, RNA-protein interaction regulation, sperm fertilization, antioxidative defense, and transcriptional regulation. Mutations in the DJ-1 gene, PARK7, are known causes of autosomal recessive parkinsonism with a clinical presentation similar to other forms of recessive PD syndromes. DJ-1 cysteine residue 106 (Cys106) is preferentially oxidized through direct oxygen addition in response to cellular oxidative stress. Cysteine forms 3 different oxidized species, cysteine–sulfenic acid (Cys-SOH), cysteine–sulfinic acid (Cys-SO2H), and cysteine–sulfonic acid (Cys-SO3H). The Cys-SO2H form of oxDJ-1 is likely the active form, and further oxidation to Cys-SO3H leads to loss of biologic function. The levels of oxDJ-1 in erythrocytes from unmedicated PD patients are reported to be markedly higher than those from medicated PD patients and healthy subjects.
