WebTitin is differentially spliced into different isoforms with and without the N2A component. The titin N2A isoform, which takes its name from this element, is the predominant isotype in skeletal muscle cells. However, the N2A element is also present in the titin N2BA isoform expressed in cardiac muscle ( Cazorla et al., 2000 ). WebTitin serves as a biological spring, spanning half of the sarcomere and connecting the Z-disk to the M-line, with scaffold and signaling functions. Truncations of titin are believed to lead to either haploinsufficiency and …

Titin definition of titin by Medical dictionary

WebTitin spans an entire half-sarcomere (∼1 μm) from Z-disk to M-line . Overlap of titin molecules in both Z-disks and M-lines produces a titin filament system that is continuous … 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 gene are found a large number of PEVK (proline-glutamate-valine-lysine -abundant See more The titin domains have evolved from a common ancestor through many gene duplication events. Domain duplication was facilitated by the fact that most domains are … See more Titin has been shown to interact with: • ANK1, • ANKRD1, • ANKRD23 See more In 1954, Reiji Natori proposed the existence of an elastic structure in muscle fiber to account for the return to the resting state when muscles are stretched and then released. … See more Titin is the largest known protein; its human variant consists of 34,350 amino acids, with the molecular weight of the mature "canonical" isoform of the protein being approximately 3,816,030.05 Da. Its mouse homologue is even larger, comprising 35,213 … See more Mutations anywhere within the unusually long sequence of this gene can cause premature stop codons or other defects.
