AbstractAggregating Dictyostelium discoideum cells possess highly specific receptors for the chemoattractant cAMP on their cell surface. Isolated membranes as well as intact cells are shown to contain a large number of latent cAMP receptors. These are reversibly unmasked in the presence of a high salt concentration (0.1–2 M) or in the presence of millimolar concentrations of Ca2+
