SLC8A1 (Sodium/Calcium Exchanger 1): SLC8A1 is a membrane transport protein that regulates the balance between sodium (Na) and calcium (Ca) ions in cardiac and skeletal muscle cells, as well as neurons. This exchanger plays a crucial role in maintaining calcium homeostasis by removing calcium from cells in exchange for sodium. Its activity is essential for muscle relaxation, preventing calcium overload, supporting proper heart and muscle function, and influencing neuronal signaling and excitability.
