PDE8A Proteins and Enzymes

Phosphodiesterase type 8 (PDE8) is one of the many phosphodiesterases that compartmentalize and hydrolyze cAMP into AMP. The cAMP-specific 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. PDE8 has a significant conserved region of about 270 amino acids common to all PDEs at the carboxy terminal apparently serves as the ...
