Abstrakt: The role of cyclic 3',5'-AMP in modulating sarcoplasmic reticulum from fast skeletal muscle was studied. The rate of Ca2+ uptake was stimulated in the presence of protein kinase plus 1 micron cyclic AMP. The stimulation was absent when denatured protein kinase was used. When an adenylate cyclase inhibitor was added, the uptake rates fell to 55% of control. This decrease in rate was partially overcome by 1 micron cyclic AMP. A modulating role for cyclic AMP in fast skeletal muscle is proposed.
