Rad53

Rad53 is a protein found in yeast cells that acts as a key part of their damage control system. When the cell encounters stress or DNA damage, Rad53 activates and helps coordinate the cell’s response—pausing cell division, repairing DNA, or halting growth to prevent errors. Think of it as a cellular emergency responder that detects trouble, signals other processes to pause, and helps organize repairs, ensuring the cell's genetic information stays accurate and stable before continuing to divide.
