Involved in photoreceptor cell morphogenesis. Located in cytoplasm and photoreceptor inner segment. Used to study cone-rod dystrophy 16 and retinitis pigmentosa. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome 21 and cone-rod dystrophy 16. Orthologous to human CFAP418 (cilia and flagella associated protein 418).
