Dyad content is reduced in cardiac myocytes of mice with impaired calmodulin regulation of RyR2
{{output}}
In cardiac muscle, calmodulin (CaM) regulates the activity of several membrane proteins involved in Ca(2+) homeostasis (CaV1.2; RyR2, SERCA2, PMCA). Three engineered amino acid substitutions in the CaM binding site of the cardiac ryanodine receptor (RyR2) in m... ...
