Model for dynamic cell polarity regulation in <i>M. xanthus</i>.

<p>The upper schematic illustrates the interactions between the Frz chemosensory module for polarity inversion (light brown background) and the MglA/MglB/RomR polarity module (light grey background). Arrows and T-bars indicate direct interactions and the stippled arrow that the molecular mechanism underlying this interaction is not known. The lower schematic illustrates the localization of the MglA, MglB and RomR proteins in a cell moving in the direction indicated by the arrow and with T4P at the leading pole. The color code is as in the upper panel.
