WebNov 15, 2016 · One of the main functions of titin is to keep the contractile elements of the sarcomere in place, and it is responsible for muscle elasticity. Titin has several sites for alternative splicing, causing isoforms of different lengths to appear in different muscles [Bang et al., Circ Res 89:1065-1072 (2001)]. WebMutations in the TTN gene cause the production of faulty titin protein, which is altered in structure and function. The defective titin protein interferes with the function of sarcomeres, disrupting normal muscle contraction. Chemical signaling is an essential process that governs cell communication and coordinates various activities inside cells.
