Functional analyses of the Dof domain, a zinc finger DNA-binding domain, in a pumpkin DNA-binding protein AOBP.

AOBP, a DNA-binding protein in pumpkin, contains a Dof domain that is composed of 52 amino acid residues and is highly conserved in several DNA-binding proteins of higher plants. The Dof domain has a significant resemblance to Cys2/Cys2 zinc finger DNA-binding domains of steroid hormone receptors and GATA1, but has a longer putative loop where an extra Cys… CONTINUE READING
