Predicted to enable cytoskeletal motor activity. Predicted to be a structural constituent of muscle. Predicted to be involved in cardiac muscle cell development and elastic fiber assembly. Predicted to act upstream of or within smooth muscle contraction. Predicted to be located in brush border; smooth muscle contractile fiber; and stress fiber. Predicted to be part of muscle myosin complex. Human ortholog(s) of this gene implicated in patent ductus arteriosus and thoracic aortic aneurysm. Orthologous to human MYH11 (myosin heavy chain 11).
