Titin is a giant multi-functional sarcomeric filament that provides passive stiffness to cardiac myocytes. At its N terminus, titin is embedded in the Z-disk of the sarcomere. The rest of the molecule is divided between an elastic I-band region, a thick filament-binding A-band region, and the M-band region … See more The extensible I-band region of titin comprises 3 distinct elements: (1) tandem Ig segments that consist of serially-linked immunoglobulin(Ig)-like domains, (2) the springlike PEVK … See more It is well-known that post-translational modifications of contractile and regulatory proteins greatly affect cardiac function. Recent single molecule force spectroscopy studies of titin have discovered that … See more Therapeutic modalities targeting titin are at present largely theoretical, but the previous discussion suggests some possibilities for consideration.
