WitrynaTropomyosin is a regulatory protein that plays its role in muscle contraction as well as intracellular transport of substances. It is found in muscle cells as a component of actin filaments as well as in the cytoskeleton of non-muscle cells. Its synthesis involves the transcription of tropomyosin genes and the translation of mRNA. WitrynaMaintenance of contractile performance of the heart is achieved in part by the constitutive 40% phosphorylation of myosin regulatory light chain (RLC) in sarcomeres. The …
