cAMP-specific 3',5'-cyclic phosphodiesterase 4D is an enzyme that in humans is encoded by the PDE4D gene.

Function

The PDE4D gene is complex and has at least 9 different isoforms that encode functional proteins. These proteins degrade the second messenger cAMP, which is a key signal transduction molecule in multiple cell types, including vascular cells (Dominiczak and McBride, 2003).[supplied by OMIM][1]

Interactions

PDE4D has been shown to interact with myomegalin[2] and GNB2L1.[3][4]

Clinical relevance

Mutations in this gene have been associated to cases of acrodysostosis.[5]

This is the subtype of PDE4 that appears to be involved in the emetic and antidepressant effects of PDE4 inhibitors.[6]

Furthermore, changes in expression of the isoform PDE4D7 have been proposed as prostate cancer biomarker. [7] [8]
