Model for Che7 regulation of development. M. xanthus responds to starvation stress by aggregating into fruiting bodies. Subsequently, a subpopulation of cells convert to resistant spores. Che7 regulates the phosphorylation state of CheY7 via the CheA7 histidine kinase. CheY7∼P interacts with HEAT repeat protein Cpc7 to inhibit sporulation prior to aggregation.
