Bacteria also have multiple homologues of actin that are involved in everything from cell division (FtsA), plasmid partitioning (ParM and AlfA), organelle organization (MamK), and regulation of cell growth and chromosome segregation (MreB). Not surprisingly, these proteins all have distinct localization patterns.
