The members of this family are similar to a region close to the C-terminus of the HipA protein expressed by various bacterial species (for example Swiss:P23874). This protein is known to be involved in high-frequency persistence to the lethal effects of inhibition of either DNA or peptidoglycan synthesis [1]. When expressed alone, it is toxic to bacterial cells [1], but it is usually tightly associated with HipB [2], and the HipA-HipB complex may be involved in autoregulation of the hip operon. The hip proteins may be involved in cell division control and may interact with cell division genes or their products [2].	Domain

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].
