Ryanodine receptors
Ryanodine receptors are specialized proteins found in the membranes of muscle cells, particularly in the heart and skeletal muscles. They act as gateways that release calcium ions from storage areas within the cell when stimulated by a signal, such as a nerve impulse. This release of calcium is crucial, as it triggers muscle contraction. Ryanodine receptors play a vital role in coordinating heartbeats and muscle movements, and their proper function is essential for overall muscle health. Dysfunction in these receptors can lead to various heart and muscle diseases.
