Predicted to enable actin monomer binding activity and tropomyosin binding activity. Involved in actin filament polymerization and sarcomere organization. Predicted to be located in actin filament; cardiac myofibril; and sarcomere. Predicted to be active in striated muscle thin filament. Predicted to colocalize with M band. Is expressed in several structures, including central nervous system; foregut; heart; lung; and skeletal musculature. Used to study dilated cardiomyopathy. Orthologous to human LMOD2 (leiomodin 2).
