Study Notes
Function of Titin in Muscle Fibers
- Titin is a giant protein that plays a crucial role in muscle contraction and elasticity.
- It connects the ends of thick filaments (myosin) to the Z disk in sarcomeres, contributing to the structural integrity of muscle fibers.
- This connection helps maintain proper alignment of thick filaments during muscle contraction and relaxation, optimizing force generation.
- Titin also helps resist excessive stretching, allowing muscles to retain their shape and function effectively during physical activity.
- By anchoring the thick filaments, titin facilitates the transmission of force from the sarcomere to the muscle fiber and ultimately to the tendon.
