Predicted to enable filamin binding activity. Predicted to be involved in several processes, including actin filament bundle organization; negative regulation of bone mineralization involved in bone maturation; and negative regulation of chondrocyte development. Predicted to act upstream of or within regulation of chondrocyte development. Predicted to be located in cytoplasm and cytoskeleton. Predicted to be active in actin filament bundle. Orthologous to human RFLNA (refilin A).
