Predicted to enable ATP hydrolysis activity; actin filament binding activity; and microfilament motor activity. Predicted to be involved in ATP metabolic process and skeletal muscle contraction. Predicted to be located in contractile fiber. Predicted to be part of myosin complex. Human ortholog(s) of this gene implicated in distal arthrogryposis type 2A; distal arthrogryposis type 2B; and distal arthrogryposis type 2B3. Orthologous to human MYH3 (myosin heavy chain 3).
