Titin muscle
WebSep 1, 2003 · In mature muscle, one of the main tasks of titin is to maintain thick filaments centrally in the sarcomere during cycles of contraction and extension. This is important, because it ensures... WebThe center of the basic unit of the muscle, the sarcomeric M-band, is perfectly placed to sense the different types of load to which the muscle is subjected. In particular, the kinase domain of titin (TK) located at the M-band is a known candidate for mechanical signaling.
