Key result
Genetic ablation of the RyR2-S2808 phosphorylation site in mice did not alter the beta-adrenergic response or protect against maladaptive cardiac remodeling induced by chronic stress.
Genetic ablation of the RyR2-S2808 phosphorylation site does not protect against heart failure progression, challenging the hypothesis that this specific phosphorylation site is a central mechanism in cardiac dysfunction.

Challenges RyR2-S2808 centrality in maladaptive remodeling; leaves open alternative mechanisms in heart failure progression.
Benkusky et al. (2007) studied Heart failure and cardiac arrhythmias. Genetic ablation of the RyR2-S2808 phosphorylation site (RyR2-S2808A) was evaluated on Beta-adrenergic response, cellular function, and protection in maladaptive cardiac remodeling. Genetic ablation of the RyR2-S2808 phosphorylation site in mice did not alter the beta-adrenergic response or protect against maladaptive cardiac remodeling induced by chronic stress.
