Entrez Gene Summary for MYH11 Gene

  • The protein encoded by this gene is a smooth muscle myosin belonging to the myosin heavy chain family. The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP. The gene encoding a human ortholog of rat NUDE1 is transcribed from the reverse strand of this gene, and its 3' end overlaps with that of the latter. The pericentric inversion of chromosome 16 [inv(16)(p13q22)] produces a chimeric transcript that encodes a protein consisting of the first 165 residues from the N terminus of core-binding factor beta in a fusion with the C-terminal portion of the smooth muscle myosin heavy chain. This chromosomal rearrangement is associated with acute myeloid leukemia of the M4Eo subtype. Alternative splicing generates isoforms that are differentially expressed, with ratios changing during muscle cell maturation. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for MYH11 Gene

MYH11 (Myosin, Heavy Chain 11, Smooth Muscle) is a Protein Coding gene. Diseases associated with MYH11 include aortic aneurysm, familial thoracic 4 and myh11-related thoracic aortic aneurysms and aortic dissections. Among its related pathways are RhoGDI Pathway and L1CAM interactions. GO annotations related to this gene include calmodulin binding and structural constituent of muscle. An important paralog of this gene is MYH4.

  • Muscle contraction

Tocris Summary for MYH11 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.
