Question

Quizplus · Accepted Answer

Actinin is a protein that connects actin filaments to the Z line, anchoring them in place. Troponin and tropomyosin are involved in regulating muscle contraction, while myosin is a motor protein that interacts with actin to generate movement. Titin is a large protein that helps to maintain the alignment of myosin and actin filaments within the sarcomere.
