Similarly , the DNA - binding activity of activator protein 1 ( AP - 1 ) is modified by a DNA repair enzyme , redox factor 1 ( Ref - 1 ) , which is identical to a DNA repair enzyme , AP endonuclease .
 GENE: activator protein 1; GENE: AP - 1; GENE: DNA repair enzyme; GENE: redox factor 1; GENE: Ref - 1; GENE: DNA repair enzyme; GENE: AP endonuclease
