Cytoskeletal protein that is involved in cell-shape control through regulation of the length of the long axis (By similarity). Probably part of the elongasome which synthesizes peripheral peptidogylcan (Probable). Interacts with MltG and MreC in the elongasome (PubMed:28710862). Interacts with KhpB (also called EloR/Jag) (PubMed:33558392). Cells are smaller. Deletion suppresses activating mutations in khpB (also called eloR/jag) (PubMed:28710862). No change in subcellular location of KhpB (PubMed:33558392). Belongs to the RodZ family.
