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 entry represents the C-terminal tetratrico peptide repeat region (TPR) of the pheromone cCF10 receptor from Enterococcus faecalis (PrgX), which serves as a molecular switch controlling expression of conjugation and virulence genes encoded by the conjugative plasmid pCF10. This region includes two domains: a large central dimerisation (and pheromone-binding) domain, and a C-terminal regulatory domain that is important for structural integrity [1,2].	Domain
