Disease

[PDE4D_HUMAN] Note=Genetic variations in PDE4D might be associated with susceptibility to stroke. PubMed:17006457 states that association with stroke has to be considered with caution. Defects in PDE4D are the cause of acrodysostosis type 2, with or without hormone resistance (ACRDYS2) [MIM:614613]. ACRDYS2 is a pleiotropic disorder characterized by skeletal, endocrine, and neurological abnormalities. Skeletal features include brachycephaly, midface hypoplasia with a small upturned nose, brachydactyly, and lumbar spinal stenosis. Endocrine abnormalities include hypothyroidism and hypogonadism in males and irregular menses in females. Developmental disability is a common finding but is variable in severity and can be associated with significant behavioral problems.^[1]

Function

[PDE4D_HUMAN] Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.^[2] ^[3]

Publication Abstract from PubMed

Cyclic nucleotide phosphodiesterases (PDEs) regulate physiological processes by degrading intracellular second messengers, adenosine-3',5'-cyclic phosphate or guanosine-3',5'-cyclic phosphate. The first crystal structure of PDE4D catalytic domain and a bound inhibitor, zardaverine, was determined. Zardaverine binds to a highly conserved pocket that includes the catalytic metal binding site. Zardaverine fills only a portion of the active site pocket. More selective PDE4 inhibitors including rolipram, cilomilast and roflumilast have additional functional groups that can utilize the remaining empty space for increased binding energy and selectivity. In the crystal structure, the catalytic domain of PDE4D possesses an extensive dimerization interface containing residues that are highly conserved in PDE1, 3, 4, 8 and 9. Mutations of R358D or D322R among these interface residues prohibit dimerization of the PDE4D catalytic domain in solution.
