Predicted to enable several functions, including RNA binding activity; actin filament binding activity; and adenyl ribonucleotide binding activity. Involved in postsynaptic actin cytoskeleton organization. Acts upstream of or within several processes, including animal organ development; generation of neurons; and plasma membrane repair. Located in several cellular components, including brush border; cytoskeleton; and growth cone. Part of myosin II complex. Is active in glutamatergic synapse. Is expressed in several structures, including early embryo; eye; heart and pericardium; neural ectoderm; and respiratory system. Orthologous to human MYH10 (myosin heavy chain 10).
