This family comprises the C-terminal portion of proteins that belong to the TetR family of transcriptional regulators. The C terminus represents the regulatory region, and does not include the DNA binding helix-turn-helix domain. The target proteins that are repressed are involved in the transcriptional control of multi-drug efflux pumps, pathways for the biosynthesis of antibiotics, response to osmotic stress and toxic chemicals, control of catabolic pathways, differentiation processes, and pathogenicity [1]. One of the target proteins is BetI, an osmoprotectant which controls the choline-glycine betaine pathway in E.coli [2].	Domain
