- Description
- Predicted to enable actin filament binding activity and microfilament motor activity. Acts upstream of or within cardiac ventricle development; embryonic heart tube development; and ventricular cardiac myofibril assembly. Predicted to be located in myofibril. Predicted to be part of myosin II complex. Predicted to be active in cytoplasm and myosin filament. Is expressed in several structures, including cardiac muscle myoblast; heart primordium; mesoderm; musculature system; and pericardial region. Human ortholog(s) of this gene implicated in cardiomyopathy (multiple); congenital heart disease (multiple); distal myopathy 1; heart conduction disease (multiple); and hyaline body myopathy (multiple). Orthologous to several human genes including MYH7 (myosin heavy chain 7).
