Involved in formation and maintenance of cell shape. Colocalizes with penicillin-binding protein PBP2 throughout the cell cycle. In newly formed and elongating cells, the foci form bands across the cell, which are predominately located at or near midcell. In cells undergoing septation, the foci are not observed at the site of septation but are positioned close to the midcell of the nascent or forming daughter cells. Belongs to the MreC family.
