Function
Protein DJ-1 or DJ-1 or PARK7 or protein/nucleic acid deglycase DJ-1 or protein deglycase DJ-1 or RNA-binding protein regulatory subunit is a cancer- and Parkinson Disease-associated protein which protects cells from toxic stresses. Dj-1 is an antioxidant and functions in transcription modulatory activity[1].
Disease
The loss of DJ-1 leads to deficits in the detoxification enzyme NADP-quinone oxidoreductase[2]. Mutations in DJ-1 caused early onset of Parkinson disease[3].
Structural highlights
The 3D structure of DJ-1 complex with the inhibitor isatin shows the covalent bond formed between isatin and DJ-1 conserved residue C106 as well as the numerous H-bonding interactions between the inhibitor and the protein[4]. Whole binding site. Water molecules are shown as red spheres.
