Titin (TTN)

Titin (TTN) is a massive protein found in our muscles, playing a crucial role in muscle contraction and elasticity. It acts like a spring, helping muscles stretch and recoil smoothly during movement. Titin is the largest known protein, consisting of thousands of amino acids, and is essential for maintaining the structure and function of muscle fibers. Mutations in the TTN gene can lead to various types of muscle disorders, such as cardiomyopathy, where the heart's ability to pump blood effectively is compromised. Overall, Titin is vital for healthy muscle function and overall physical performance.
