Occurrence of the alpha subunits of G proteins in cerebral cortex synaptic membrane and postsynaptic density fractions: modulation of ADP-ribosylation by Ca2+/calmodulin.
We have examined the isolated postsynaptic density (PSD) fraction for the presence of a G protein. First, we found specific binding of guanosine 5'-[gamma-[35S]thio]triphosphate to the PSD. Second, pertussis toxin-activated ADP-ribosylation of the isolated PSD fraction resulted in the appearance of...
