DJ-1 (PARK 7) protects against oxidative stress and cell death, is a positive regulator of androgen-receptor dependent rtanscription, but has not been found in the neural retina or retinal pigment epithelium of mammals.
DJ-1 is expressed in both the neural retina and retinal pigment epithelium of mammals, where it exerts a neuroprotective role against oxidative stress under both physiological and pathological conditions.
