Predicted to enable cytoskeletal motor activity. Predicted to be a structural constituent of muscle. Predicted to be involved in muscle filament sliding and skeletal muscle tissue development. Predicted to be part of unconventional myosin complex. Is expressed in central nervous system; diaphragm; limb mesenchyme; skeletal musculature; and tail paraxial mesenchyme. Orthologous to human MYL6B (myosin light chain 6B). [provided by Alliance of Genome Resources, Apr 2022]
