death domain

The death domain is a specific region found in certain proteins involved in controlling cell death, or apoptosis. It acts as a signaling hub that allows these proteins to communicate and initiate the process of dismantling a cell when it is no longer needed or is damaged. This domain helps regulate immune responses and maintains tissue health by ensuring that faulty or dangerous cells are efficiently removed, preventing potential diseases like cancer or autoimmune disorders. In essence, the death domain is a key part of the body's system for safely and precisely managing cell life and death.
