Two cAMP receptors activate common signaling pathways in Dictyostelium.


Multiple signal transduction pathways within a single cell may share common components. In particular, seven different transmembrane helix receptors may activate identical pathways by interacting with the same G-proteins. Dictyostelium cells respond to cAMP using one such receptor, cAR1, coupled by a typical heterotrimeric G-protein to intracellular… (More)
