One of the many phosphodiesterases that compartmentalized and hydrolyze cAMP into AMP is phosphodiesterase type 8. The cAMP-specific phosphodiesterase type 8 (PDE8) family is comprised of 2 genes (PDE8A and PDE8B) each with multiple splice variants generated by RNA splicing and use of alternate initiation sites. PDE8 family is a high affinity cAMP-specific, IBMX sensitive PDE. The PDE8 has a significant conserved region of about 270 amino acids common to all PDEs at the carboxy terminal apparently serves as the catalytic domain. The amino-terminal region of this protein is divergent and presumably accounts for the distinctive and regulatory properties unique to the individual PDE families. PDE8A protein showed significant homology to other cAMP-dependent PDEs (23%) within the catalytic domain. PDE8A is widely expressed in various tissues in contrast to PDE8B that is exclusively expressed in thyroid gland. The PDE8A transcripts are found in brain, pancreas, placenta, thyroid, spleen, trachea, prostate, and uterus.
