This large family of DNA binding helix-turn helix proteins includes Cro Swiss:P03036 and CI Swiss:P03034. Within the protein Swiss:Q5F9C2, the full protein fold incorporates a helix-turn-helix motif, but the function of this member is unlikely to be that of a DNA-binding regulator, the function of most other members, so is not necessarily characteristic of the whole family [1].

This is a putative DNA-binding protein dimerization domain found bacterial proteins such as CD3330, (a transposon-related DNA-binding protein from Clostridium difficile). Crystal structure analysis suggests that CD3330 N-terminus is involved in dimer formation and also in crystal packing but the C-terminus is open to solvent [1].	Domain
