Enables 3',5'-cyclic-AMP phosphodiesterase activity; gamma-tubulin binding activity; and transmembrane transporter binding activity. Involved in several processes, including cellular response to epinephrine stimulus; negative regulation of adenylate cyclase-activating adrenergic receptor signaling pathway involved in heart process; and regulation of muscle system process. Acts upstream of or within several processes, including cellular response to lipopolysaccharide; neutrophil chemotaxis; and neutrophil homeostasis. Located in several cellular components, including Z disc; centrosome; and synaptic vesicle. Part of gamma-tubulin complex and voltage-gated calcium channel complex. Is expressed in several structures, including alimentary system; ear; genitourinary system; nervous system; and respiratory system. Orthologous to human PDE4B (phosphodiesterase 4B).
