Where Is Titin Located In The Muscle? Titin is a huge, 4.2 MDa, filamentous protein located in the sarcomere What is titin in muscle contraction? Titin has long been recognized as a mechanical protein in muscle cells that has a main function as a molecular spring in the contractile units, the sarcomeres. Recent work suggests
