Acts upstream of or within photoreceptor cell outer segment organization and protein localization to photoreceptor outer segment. Located in photoreceptor inner segment and photoreceptor outer segment. Is expressed in eye. Used to study retinitis pigmentosa 54. Human ortholog(s) of this gene implicated in retinitis pigmentosa 54. Orthologous to human PCARE (photoreceptor cilium actin regulator). [provided by Alliance of Genome Resources, Apr 2022]
