The protein that acts as a calcium receptor in skeletal muscle is __________.

Question

Quizplus · Accepted Answer

Troponin is the protein that acts as a calcium receptor in skeletal muscle. When calcium binds to troponin, it causes a conformational change in the troponin-tropomyosin complex, uncovering the myosin binding sites on actin, and allowing for muscle contraction to occur. F actin, titin, and dystrophin are all structural proteins in muscle, while tropomyosin is part of the troponin-tropomyosin complex, but not the calcium receptor itself.
