checkpoint kinases

Checkpoint kinases are specialized enzymes that act as quality control agents during cell division. They monitor the integrity of DNA and other cellular processes to ensure everything is accurate before a cell divides. If they detect damage or errors, these kinases can pause the division process, allowing repairs to be made and preventing the spread of mistakes. By doing so, they help maintain healthy cell function and prevent mutations that could lead to diseases like cancer. In essence, checkpoint kinases serve as critical guardians, coordinating proper cell cycle progression and genomic stability.
