Ring domain #1CHC. The RING finger is a specialized type of Zn finger consisting of 40–60 residues that binds two atoms of zinc, and is involved in mediating protein—protein interactions. Many zinc fingers bind nucleic acids. The presence of a RING finger domain is a characteristic of RING-class E3 ubiquitin protein ligases capable of transferring ubiquitin from an E2 enzyme to a substrate protein.
