Myosin is a major contractile protein which converts chemical energy into mechanical energy through the hydrolysis of ATP. Myosin is a hexameric protein composed of a pair of myosin heavy chains (MYH) and two pairs of nonidentical light chains. Myosin heavy chains are encoded by a multigene family. In mammals at least 10 different myosin heavy chain (MYH) isoforms have been described from striated, smooth, and nonmuscle cells. These isoforms show expression that is spatially and temporally regulated during development. [provided by RefSeq, Jul 2008]
GeneCards Summary for MYH1 Gene
MYH1 (Myosin, Heavy Chain 1, Skeletal Muscle, Adult) is a Protein Coding gene. Diseases associated with MYH1 include familial gastric cancer. Among its related pathways are RhoGDI Pathway and ERK Signaling. GO annotations related to this gene include actin binding and motor activity. An important paralog of this gene is MYH4.
UniProtKB/Swiss-Prot for MYH1 Gene
Myosins are a large family of motor proteins that share the common features of ATP hydrolysis, actin binding and potential for kinetic energy transduction. Originally isolated from muscle cells (hence the name), almost all eukaryotic cells are now known to contain myosins. Structurally, mysoins contain a head domain that binds to actin filaments (microfilaments) and is the site of ATP hydrolysis. The tail domain interacts with cargo molecules, and the neck acts as a linker between the head and tail and is the site of regulatory myosin light chain binding. There are 17 myosin families and the most well characterized is myosin II. Myosin II is found predominantly in myocytes and mediates plus-ended movement along microfilaments. It is involved in muscle contraction through cyclic interactions with actin-rich thin filaments, creating a contractile force. It is regulated by phosphorylation via myosin light chain kinase (MLCK) and by intracellular Ca2+ concentrations.
