WebTitin is the largest protein chain in your body, with more than 34,000 amino acids. This titanic protein acts like a big rubber band in our muscles. It is attached at one end to the Z … Titin is a large abundant protein of striated muscle. Titin's primary functions are to stabilize the thick filament, center it between the thin filaments, prevent overstretching of the sarcomere, and to recoil the sarcomere like a spring after it is stretched. An N-terminal Z-disc region and a C-terminal M-line … See more Titin /ˈtaɪtɪn/ (contraction for Titan protein) (also called connectin) is a protein that in humans is encoded by the TTN gene.

WebJul 11, 2012 · Titin being a filamentous shaped protein is able to its job in striated muscles. [1] The molecules are formed with bands themselves and when they form sacromeres they line up next to one another in a linear fashion. The structure is able to give an idea on how it relates to the function and how titin works as an elastic in muscles. WebThe elastic behavior of muscle has been described as consisting of two major components. The parallel elastic component (PEC), provided by the muscle membranes, supplies resistance when a muscle is passively stretched. The series elastic component (SEC), residing in the tendons, acts as a spring to store elastic energy when a tensed muscle is …
