Predicted to enable 3',5'-cyclic-nucleotide phosphodiesterase activity. Acts upstream of or within photoreceptor cell maintenance and retina development in camera-type eye. Predicted to be located in plasma membrane. Predicted to be active in photoreceptor outer segment membrane. Is expressed in retina outer nuclear layer. Used to study retinitis pigmentosa. Human ortholog(s) of this gene implicated in retinitis pigmentosa 43. Orthologous to human PDE6A (phosphodiesterase 6A). [provided by Alliance of Genome Resources, Apr 2022]
