In both cardiac and slow-twitch skeletal muscle sarcoplasmic reticulum (SR) there are several systems involved in the regulation of Ca(2+)-ATPase function. These include substrate level regulation, covalent modification via phosphorylation-dephosphorylation of phospholamban by both cAMP-dependent protein kinase (PKA) and Ca2+/calmodulin-dependent protein kinase (CaM kinase) as well as direct CaM kinase phosphorylation of the Ca(2+)-ATPase. Studies comparing the effects of PKA and CaM kinase on… CONTINUE READING
