Predicted to enable 3',5'-cyclic-nucleotide phosphodiesterase activity. Predicted to be involved in retina development in camera-type eye and signal transduction. Predicted to act upstream of or within photoreceptor cell maintenance. Predicted to be active in photoreceptor outer segment membrane. 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]
