Parkinson disease (autosomal recessive, early onset) 7, also known as PARK7, is a protein which in humans is encoded by the PARK7 gene.[2] It is also known as DJ-1.


PARK7 belongs to the peptidase C56 family of proteins. It acts as a positive regulator of androgen receptor-dependent transcription. It may also function as a redox-sensitive chaperone, as a sensor for oxidative stress, and it apparently protects neurons against oxidative stress and cell death.[2]

Clinical significance[edit]

Defects in this gene are the cause of autosomal recessive early-onset Parkinson's disease 7.[2][3]


PARK7 has been shown to interact with EFCAB6[4] and Protein inhibitor of activated STAT2.[5]
