The cAMP-specific phosphodiesterase (PDE) HSPDE 4A4B(pde46) selectively bound SH3 domains of SRC family tyrosyl kinases. Such an interaction profoundly changed the inhibition of PDE4 activity caused(More)
Transfection of COS7 cells with a plasmid encoding the human cyclic AMP-specific PDE4A phosphodiesterase PDE-46 (HSPDE4A4B) led to the expression of a rolipram-inhibited PDE4 activity, which(More)
The long cyclic AMP (cAMP)-specific phosphodiesterase isoform, PDE4A5 (PDE4A subfamily isoform variant 5), when transiently expressed in COS-7 cells, was shown in subcellular fractionation studies to(More)
A 25-residue peptide representing the membrane targeting N-terminal splice region of the cyclic AMP phosphodiesterase RD1 (RNPDE4A1) was synthesized, and its structure was determined by 1H NMR. Two(More)
Here we identify an 11-residue helical module in the unique N-terminal region of the cyclic AMP-specific phosphodiesterase PDE4A1 that determines association with phospholipid bilayers and shows a(More)
