Protein Repair Mechanisms
Protein repair mechanisms are essential processes that help maintain the integrity and functionality of proteins within cells. Proteins can become damaged due to various factors, such as oxidative stress, heat, or chemical exposure. These mechanisms involve several pathways, including chaperones, which assist in refolding misfolded proteins, and proteolytic enzymes, which degrade irreparably damaged proteins to prevent cellular dysfunction.
Additionally, cells utilize post-translational modifications to repair or mark damaged proteins for degradation. These modifications can alter the protein's structure or signal for its removal. Overall, protein repair mechanisms are crucial for cellular health and longevity, ensuring that proteins perform their necessary functions effectively.
