title: Bacterial border fence.
abstract: Bacteria lack many of the features that eukaryotic cells use to compartmentalize cytoplasm and membranes. In this issue, Schlimpert et al. describe a new mechanism of spatial confinment in the bacterium Caulobacter crescentus that prevents the exchange of soluble and membrane proteins between the stalk and cell body.
