Proteins within the intracellular calcium store determine cardiac RyR channel activity and cardiac output
The contractile function of the heart requires the release of Ca2+ from intracellular Ca2+ stores in the sarcoplasmic reticulum (SR) of cardiac muscle cells. The efficacy of Ca2+ release depends on the amount of Ca2+ loaded into the Ca2+ store and the way in which this 'Ca2+ load' influences the activity of the cardiac ryanodine receptor Ca2+ release channel (RyR2). The effects of the Ca2+ load on Ca2+ release through RyR2 are facilitated by: (i) the sensitivity of RyR2 itself to luminal Ca2+...[Show more]
