DNA-PK
DNA-PK (DNA-dependent protein kinase) is an enzyme essential for repairing DNA double-strand breaks, which are serious damage to the genetic material. It detects the break, then activates the repair process by assembling with other proteins to rejoin the broken DNA strands correctly. This process helps maintain genetic stability, preventing mutations that could lead to diseases like cancer. DNA-PK plays a crucial role in the cell's ability to fix its DNA efficiently, ensuring proper cell function and health.
