| Abstract: | Recent studies have established that the eukaryotic actin-based cytoskeleton has prokaryotic origins. In addition to regulating cell shape and polarity, Gitai et al. (2005) provide convincing evidence that the Caulobacter actin homolog MreB also mediates the early segregation of the chromosomal origin, a typical functional role of the eukaryotic tubulin-based cytoskeleton. |
