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. Titin is a giant protein, greater than 1 µm in length, that functions as a molecular spring that is responsible … See more The human gene encoding for titin is located on the long arm of chromosome 2 and contains 363 exons, which together code for 38,138 amino acid residues (4200 kDa). Within the … See more The titin domains have evolved from a common ancestor through many gene duplication events.

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 TTN gene provides instructions for making a very large protein called titin. This protein plays an important role in skeletal muscles, which the body uses for movement, and in heart (cardiac) muscle. Slightly different versions (called isoforms) of titin are made from the TTN gene in different muscles..
