- _5 value "PDE3A (phosphodiesterase 3A) was identified as a phosphoprotein that co-immunoprecipitates with endogenous 14-3-3 proteins from HeLa cell extracts, and binds directly to 14-3-3 proteins in a phosphorylation-dependent manner (Ser428). Among cellular stimuli tested, PMA promoted maximal binding of PDE3A to 14-3-3 proteins. While p42/p44 MAPK (mitogen-activated protein kinase), SAPK2 (stress-activated protein kinase 2)/p38 and PKC (protein kinase C) were all activated by PMA in HeLa cells, the PMA-induced binding of PDE3A to 14-3-3 proteins was inhibited by the non-specific PKC inhibitors Ro 318220 and H-7, but not by PD 184352, which inhibits MAPK activation, nor by SB 203580 and BIRB0796, which inhibit SAPK2 activation." provenance.
