Dysfunction of the nitric oxide/mechano-electrical signaling pathways are likely to be a feature of cardiac pathology (e.g., atrial fibrillation, cardiomyopathy, and heart failure) and a better understanding of the importance of nitric oxide signaling and its links to mechanical regulation of heart function may advance our understanding of these conditions. Nitric oxide (NO) is a short-lived, gaseous signaling molecule that is produced endogenously by a family of enzymes called the nitric oxide synthases (NOS), which catalyze the synthesis of NO from the amino acid arginine (Bredt, 1999).

Kingwell BA(1). Protein–protein interactions among caveolin-1, calmodulin, and eNOS appear to alter availability of eNOS to signals within the caveolae; hence, a regulatory cycle exists, wherein Ca 2+ /calmodulin releases eNOS from the scaffolding domain of caveolin-1, thus permitting enzyme activity (97).
