Web31 Jan 2024 · 605 5 14. think of it this way : the thin filaments are attached to the Z-line (with the help of Z -disc) and thick filaments with the help of a spring like protein (titin). Now, when contraction occurs, myosin head pulls the actin filament towards it (power stroke) : i.e. Z-line is pulled towards the centre and the length of sarcomere shortens. WebThis review focuses on what molecular mechanisms may underlie myofilament length dependency. Specifically, the roles of inter-filament spacing, thick and thin filament based regulation, as well as sarcomeric regulatory proteins are discussed.
