Ftsz, mreb, and cres ,proteins regulate the shape and structure of bacterial prokaryotic cells. These proteins are homologous to the Cytoskeleton in eukaryotes. Homologous meaning they have the same evolutionary origin but not necessarily having the same function. Cytoskeleton forms a framework for the movement of organelles around the cytoplasm, most organelles are attached to the cytoskeleton.
