Summaries for MYH8 Gene

Entrez Gene Summary for MYH8 Gene

  • Myosins are actin-based motor proteins that function in the generation of mechanical force in eukaryotic cells. Muscle myosins are heterohexamers composed of 2 myosin heavy chains and 2 pairs of nonidentical myosin light chains. This gene encodes a member of the class II or conventional myosin heavy chains, and functions in skeletal muscle contraction. This gene is predominantly expressed in fetal skeletal muscle. This gene is found in a cluster of myosin heavy chain genes on chromosome 17. A mutation in this gene results in trismus-pseudocamptodactyly syndrome. [provided by RefSeq, Sep 2009]

GeneCards Summary for MYH8 Gene

MYH8 (Myosin, Heavy Chain 8, Skeletal Muscle, Perinatal) is a Protein Coding gene. Diseases associated with MYH8 include carney complex variant and trismus-pseudocamptodactyly syndrome. Among its related pathways are RhoGDI Pathway and ERK Signaling. GO annotations related to this gene include actin binding and structural constituent of muscle. An important paralog of this gene is MYH4.

  • Muscle contraction

Tocris Summary for MYH8 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.

(2) OMIM Diseases for MYH8 Gene (160741)


  • Carney complex variant (CACOV) [MIM:608837]: Carney complex is a multiple neoplasia syndrome characterized by spotty skin pigmentation, cardiac and other myxomas, endocrine tumors, and psammomatous melanotic schwannomas. Familial cardiac myxomas are associated with spotty pigmentation of the skin and other phenotypes, including primary pigmented nodular adrenocortical dysplasia, extracardiac (frequently cutaneous) myxomas, schwannomas, and pituitary, thyroid, testicular, bone, ovarian, and breast tumors. Cardiac myxomas do not develop in all patients with the Carney complex, but affected patients have at least two features of the complex or one feature and a clinically significant family history. {ECO:0000269 PubMed:15282353}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Arthrogryposis, distal, 7 (DA7) [MIM:158300]: A form of distal arthrogryposis, a disease characterized by congenital joint contractures that mainly involve two or more distal parts of the limbs, in the absence of a primary neurological or muscle disease. DA7 is characterized by an inability to open the mouth fully (trismus) and pseudocamptodactyly in which wrist dorsiflexion, but not volarflexion, produces involuntary flexion contracture of distal and proximal interphalangeal joints. Additional features include shortened hamstring muscles and short stature. {ECO:0000269 PubMed:15282353, ECO:0000269 PubMed:20949528}. Note=The disease is caused by mutations affecting the gene represented in this entry.
