Titin

Titin is a giant protein found in muscle cells, playing a crucial role in muscle elasticity and function. It acts like a molecular spring, allowing muscles to stretch and recoil without damage, contributing to muscle flexibility and strength. Titin connects the tiny structures within muscle fibers, helping maintain their shape and structure during contraction and relaxation. Due to its size and complexity, titin is the largest known protein, and its proper function is essential for healthy muscle movement. Mutations or malfunctions in titin can lead to muscle diseases and disorders.
