Predicted to enable actin filament binding activity. Predicted to be involved in actin filament bundle assembly; cell migration; and establishment or maintenance of cell polarity. Predicted to act upstream of or within eye photoreceptor cell development. Predicted to be located in stereocilium. Predicted to be active in actin cytoskeleton and cytoplasm. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 30. Orthologous to human FSCN2 (fascin actin-bundling protein 2, retinal).
