Atg proteins

ATG proteins are a group of specialized proteins that regulate autophagy, a vital process where cells break down and recycle their own components to maintain health and balance. Think of them as organizers and managers that initiate, oversee, and complete the cell’s cleaning process. During autophagy, ATG proteins help form structures called autophagosomes—like cellular recycling containers—that capture damaged parts or unnecessary materials. This process supports cell survival under stress, removes harmful debris, and maintains overall cellular health, which is essential for preventing diseases and supporting normal biological functions.
