1 AIMS: The cardiac ryanodine receptor (RyR2), which mediates intracellular Ca2+ release to trigger cardiomyocyte contraction, participates in development of acquired and inherited arrhythmogenic cardiac disease. Calcium ryanodine receptor 2 Homo sapiens
2 We also show that the RyR2 N-terminus domain interacts with the C-terminal channel pore region in a Ca2+-independent manner. Calcium ryanodine receptor 2 Homo sapiens
3 Therapeutic strategies currently focus on gain-of-function RyR2 channels to suppress sarcoplasmic reticulum Ca2+ release either indirectly with class I/II anti-arrhythmic drugs, or by directly targeting RyR2 to inhibit channel activity. Calcium ryanodine receptor 2 Homo sapiens
