Predicted to enable 3',5'-cyclic-nucleotide phosphodiesterase activity. Involved in retinal cell apoptotic process. Predicted to be located in photoreceptor outer segment. Predicted to be active in photoreceptor outer segment membrane. Used to study retinitis pigmentosa. Human ortholog(s) of this gene implicated in congenital stationary night blindness autosomal dominant 2 and retinitis pigmentosa 40. Orthologous to human PDE6B (phosphodiesterase 6B).
