Predicted to enable 3',5'-cyclic-AMP phosphodiesterase activity; 3',5'-cyclic-GMP phosphodiesterase activity; and kinase binding activity. Predicted to be involved in several processes, including cellular response to epidermal growth factor stimulus; negative regulation of hydrogen peroxide-induced cell death; and positive regulation of ERK1 and ERK2 cascade. Orthologous to human PDE8A (phosphodiesterase 8A). [provided by Alliance of Genome Resources, Apr 2022]
