Sir2

Sir2 is a type of protein known as a deacetylase that plays a key role in regulating cell functions, especially related to aging and longevity. It influences how genes are turned on or off by modifying other proteins called histones, which help package DNA. By removing acetyl groups from these histones, Sir2 can promote gene stability and repair, helping cells maintain their health over time. It is also linked to the benefits of calorie restriction and has been studied for its potential in extending lifespan and improving age-related health.
