Calcium 23-30 ryanodine receptor 2, cardiac Mus musculus 42-46 16407108-3 2006 In patients with heart failure, chronic activation of the "fight or flight" stress response leads to protein kinase A (PKA) hyperphosphorylation of RyR2 at Ser-2808. Serine 156-159 ryanodine receptor 2 Homo sapiens 148-152 16407108-4 2006 PKA phosphorylation of RyR2 Ser-2808 reduces the binding affinity of the channel-stabilizing subunit calstabin2, resulting in leaky RyR2 channels. Serine 28-31 ryanodine receptor 2, cardiac Mus musculus 23-27 16407108-4 2006 PKA phosphorylation of RyR2 Ser-2808 reduces the binding affinity of the channel-stabilizing subunit calstabin2, resulting in leaky RyR2 channels. Serine 28-31 FK506 binding protein 1b Mus musculus 101-111 16407108-4 2006 PKA phosphorylation of RyR2 Ser-2808 reduces the binding affinity of the channel-stabilizing subunit calstabin2, resulting in leaky RyR2 channels. Serine 28-31 ryanodine receptor 2, cardiac Mus musculus 132-136 16407108-7 2006 Taken together, these data show that PKA phosphorylation of Ser-2808 on the RyR2 channel appears to be a critical mediator of progressive cardiac dysfunction after myocardial infarction. Serine 60-63 ryanodine receptor 2, cardiac Mus musculus 76-80
