WebApr 12, 2024 · Rationale: Mavacamten is a novel, FDA-approved, small molecule therapeutic designed to regulate cardiac function at the sarcomere level by selectively but reversibly inhibiting the enzymatic activity of myosin. It shifts myosin towards ordered off states close to the thick filament backbone. Objective: The purpose of this study is to investigate … Myosin is a contractile protein found in the muscles of animals as well as non-muscle cells. It is responsible for muscle contraction as well as intracellular transport. Myosin is made of six subunits including two heavy chains and four light chains. The molecule is considered to be made up of three … See more The contraction of skeletal muscles is responsible for all kinds of movements exhibited by animals. This contraction is possible due to the … See more Myosin is a protein that can be synthesized by almost all the cells in the process of gene expression. The genes for myosin molecules are present on different chromosomes, depending on the class of molecules.
