Predicted to enable actin monomer binding activity and tropomyosin binding activity. Predicted to be involved in several processes, including actin nucleation; muscle cell development; and positive regulation of skeletal muscle fiber development. Predicted to be located in M band. Predicted to be active in striated muscle thin filament. Human ortholog(s) of this gene implicated in nemaline myopathy 10. Orthologous to human LMOD3 (leiomodin 3).
