Anti-phospholamban and protein kinase A alter the Ca2+ sensitivity and maximum velocity of Ca2+ uptake by the cardiac sarcoplasmic reticulum.
The activity of the SERCA2a Ca2+ pump in the sarcoplasmic reticulum (SR) of cardiac muscle is inhibited by phospholamban. When phospholamban is phosphorylated by cyclic-AMP-dependent protein kinase (PKA) this inhibition is relieved. It is generally agreed that this results in an increase in the Ca2+...
