Cyclic AMP modulation of calcium accumulation by sarcoplasmic reticulum from fast skeletal muscle. 1977

E P Bornet, and M L Entman, and W B Van Winkle, and A Schwartz, and D C Lehotay, and G S Levey

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.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
