Phosphorylation of Cardiac Ryanodine Receptors
FY 2016-17
Summary
Our hearts require calcium ions to contract. These calcium ions get released from a special store through a gate. The gate is formed by a protein, known as the Ryanodine Receptor. It is absolutely crucial that the gate opens and closes at appropriate time points. Any deviation can lead to excessive calcium, with a resulting cardiac arrhythmia. In some cases, the gate dysfunctions because of a genetic mutation. Such mutations lead to stress-induced arrhythmias and the patients are at risk for sudden cardiac death. In other cases, aging can result in small modifications of the gate, causing it to open too easily. This is a situation often occurring in heart failure, a conditions affecting ~600,000 Canadians. The resulting arrhythmia can often be fatal. This project aims to study how the gate dysfunctions due to the small modifications.
