Predicted to enable actin filament binding activity. Predicted to be involved in several processes, including actin filament fragmentation; actin filament severing; and positive regulation of actin filament depolymerization. Predicted to act upstream of or within actin filament organization; muscle cell cellular homeostasis; and sarcomere organization. Predicted to be located in Z disc. Predicted to be active in actin cytoskeleton and cytoplasm. Human ortholog(s) of this gene implicated in nemaline myopathy 7. Orthologous to human CFL2 (cofilin 2).
