Maintenance of whole cell isoproterenol and forskolin responsiveness in adenylate cyclase of permeabilized cells.


Digitonin-permeabilized monolayers of C6-2B rat astrocytoma cells exhibit adenylate cyclase activity in the presence of exogenously added ATP. The adenylate cyclase retains the qualitative and quantitative characteristics of hormone stimulated cyclic AMP accumulation in whole cells including GTP dependency and 100 fold stimulation by isoproterenol… (More)
