Predicted to enable spectrin binding activity. Acts upstream of or within positive regulation of G protein-coupled receptor signaling pathway; positive regulation of MAPK cascade; and positive regulation of epidermal growth factor receptor signaling pathway. 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 57. Orthologous to human PDE6G (phosphodiesterase 6G). [provided by Alliance of Genome Resources, Apr 2022]
