Proteins/UNIPROT:Q13370
Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological process. Regulates angiogenesis by inhibiting the cAMP-dependent guanine nucleotide exchange factor RAPGEF3 and downstream phosphatidylinositol 3-kinase gamma-mediated signaling. Controls cardiac contractility by reducing cAMP concentration in cardiocytes (By similarity)..
