Dihydropyridine receptor
The dihydropyridine receptor (DHPR) is a type of protein found in muscle cell membranes, acting as a calcium channel. It plays a crucial role in muscle contraction by sensing electrical signals and triggering the release of calcium from internal stores. This calcium release then allows muscle fibers to contract and generate movement. Located in specialized areas of the cell membrane, DHPRs also serve as sensors that communicate with internal structures, coordinating the muscle's response to stimulation. Overall, they are essential for proper muscle function and coordination.
