DR5 (Death Receptor 5)

DR5 (Death Receptor 5) is a protein found on the surface of certain cells that plays a key role in regulating cell death, also known as apoptosis. It binds to specific molecules, triggering a cascade of signals that lead to cell self-destruction. This process is important for removing damaged or unwanted cells, helping maintain healthy tissue function and preventing issues like cancer. In some therapies, scientists target DR5 to induce death in cancer cells, making it a promising focus for treatments that aim to selectively eliminate harmful cells.
