Summary: Enables actin filament binding activity and microfilament motor activity. A structural constituent of muscle. Involved in several processes, including egg-laying behavior; muscle contraction; and skeletal muscle myosin thick filament assembly. Located in A band and striated muscle myosin thick filament. Part of muscle myosin complex. Is expressed in several structures, including body wall musculature; enteric muscle; germ line; intestinal cell; and vulval muscle. Human ortholog(s) of this gene implicated in several diseases, including cardiomyopathy (multiple); congenital heart disease (multiple); contractures, pterygia, and spondylocarpotarsal fusion syndrome (multiple); heart conduction disease (multiple); and muscle tissue disease (multiple). Orthologous to several human genes including MYH1 (myosin heavy chain 1); MYH13 (myosin heavy chain 13); and MYH15 (myosin heavy chain 15). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Moderate dietary restriction delays the onset of age-associated sarcopenia in Caenorhabditis elegans due to reduced myosin UNC-54 degradation.
Title: Moderate dietary restriction delays the onset of age-associated sarcopenia in Caenorhabditis elegans due to reduced myosin UNC-54 degradation.
Cautionary note on the use of Caenorhabditis elegans to study muscle phenotypes caused by mutations in the human MYH7 gene.
Title: Cautionary note on the use of Caenorhabditis elegans to study muscle phenotypes caused by mutations in the human MYH7 gene.
In C. elegans, mutant alleles of the myosin heavy chain gene unc-54 corresponding to R1845W, E1883K and H1901L, were as effective as the wild-type myosin gene in rescuing the null mutant worms, indicating that they retain functionality.
