Abstract

In conditions of starvation, the free living amoebae of enter a developmental program: The cells aggregate by chemotaxis to form a multicellular structure that undergoes morphogenesis and cell-type differentiation. These processes are mediated by a family of cell surface CAMP receptors (CARS) that act on a specific heterotrimeric G protein to stimulate actin polymerization, activation of adenylyl and guanylyl cyclases, and a host of other responses. Most of the components in these pathways have mammalian counterparts. The accessible genetics of this unicellular organism facilitate structure-function analysis and enable the discovery of novel genes involved in the regulation of these important pathways.
