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 domain is found at the C-terminal end of HTH-type transcriptional regulator Rgg from Streptococcus gordonii, and similar proteins predominantly found in Firmicutes. Rgg is a peptide pheromone receptor that directly binds pheromones transported to the cytosol. The large C-terminal repeat domain contains five HTH folds and a capping helix that form a right-handed superhelical structure, resembling a TPR domain superhelix [1-5]. This domain is found associated with the N-terminal Pfam:PF01381.	Domain
