Ku proteins

Ku proteins are essential molecules in human cells that play a crucial role in repairing DNA. When DNA is damaged, which can happen due to environmental factors or errors during cell division, Ku proteins help detect the break. They bind to the broken ends of DNA, acting like a molecular glue. This binding is the first step in a series of events that allow the cell to fix the damage, ensuring that genetic information remains intact and reducing the risk of diseases like cancer. In short, Ku proteins are vital for maintaining the integrity of our DNA.
