Adenosine 3',5'-cyclic monophosphate (cyclic AMP) and its 8-methylthio derivative stimulate the incorporation of 32P into proteins endogenous to a homogenate of rat caudate nucleus when 4 micrometer [gamma-32P] ATP is used as substrate. Higher concentrations of ATP reduced the effect of the cyclic nucleotide until at 400 micrometer no significant increase in protein phosphorylation was seen. Incubation of the homogenate with 400 micron ATP and 100 micron dopamine resulted in an approx. 2-fold increase in cyclic AMP but did not alter caudate protein phosphorylation suggesting that the catecholamine could not stimulate protein phosphorylation under the experimental conditions used in the present study. |
