What are the thin myofilaments of a sarcomere called?

WebThe thick filaments are anchored at the middle of the sarcomere (the M-line) by a protein called myomesin. The lighter I band regions contain thin actin filaments anchored at the Z-discs by a protein called α-actinin. The thin filaments extend into the A band toward the M-line and overlap with regions of the thick filament. WebJun 8, 2024 · Myofibrils are composed of smaller structures called myofilaments.
