The helix-turn-helix (HTH) motif in the cytoplasmic domain of the N-terminus is involved in the formation of spirals to maintain the rigid rod shape. As this protein is anchored in the cytoplasmic membrane, the HTH motif may contribute to protein-protein interactions to form the RodZ helix, which is localized beneath the cytoplasmic membrane. The C-terminal domain may be critical for determination of the rod shape by probably interacting with enzymes required for synthesis of the peptidoglycan layer, including PBPs in the periplasm (By similarity).
