Myofilament: the Specialized proteins of Myofibrils - BrainKart

WebThe myofibrils have myofilaments inside. They are arranged parallel to each other. There are thick (myosin) and thin filaments (actin) that slide onto each other. The protein (actin) contributing to the myofilaments belong to the group of cytoskeletal proteins - microfilaments. The myofilaments are arranged in a functional unit known as sarcomere. There are three different types of myofilaments: thick, thin, and elastic filaments. • Thick filaments consist primarily of a type of myosin, a motor protein – myosin II.
