WebJul 20, 2024 · We found that an N-terminal fragment of titin (also known as connectin) is detectable in urine after eccentric exercise. We then established a quantitative enzyme-linked immunosorbent assay (ELISA) to measure the urinary titin fragment, and evaluated the utility of the urinary titin fragment as a biomarker of exercise-induced muscle damage. WebTitin (and its splice isoforms) is the biggest single highly elasticated protein found in nature. It provides binding sites for numerous proteins and is thought to play an important role as sarcomeric ruler and as blueprint for the assembly of the sarcomere. red curry ohje

WebJan 20, 2024 · Titin has been associated with a variety of functions, including mechanical roles in active and passive force regulation in cardiac and skeletal muscles (e.g., Linke et al. 1994, 1996; Granzier and Labeit 2002, 2007; Linke and Fernandez 2002; Herzog et al. 2006; LeWinter and Granzier 2010; Herzog 2014a ), structural and developmental roles in … Webmade from the TTN gene in different muscles. Within muscle cells, titin is an essential component of structures called sarcomeres. Sarcomeres are the basic units of muscle tensing (contraction); they are made of proteins that generate the mechanical force needed for muscles to contract. Titin has several functions within sarcomeres.
