We raised a polyclonal antibody against maltose binding protein fusion human cGMP-binding, cGMP-specific phosphodiesterase (PDE5) produced in E. coli. This antibody immunoreacted specifically with recombinant human and rat PDE5 proteins expressed in transfected COS-7 cells and with a native form of PDE5 in extracts of rat platelets, lung, and cerebellum. Immunohistochemical analysis showed that the anti-PDE5 antibody detected immunoactive materials in Purkinje cell layers of the cerebellum, proximal renal tubules, collecting renal ducts, and epithelial cells of pancreatic ducts in rats. Reverse transcriptase-polymerase chain reaction analysis demonstrated that PDE5 transcripts are also present in rat cerebellum, kidney, and pancreas. Here we described a cell-specific localization of PDE5 in various rat tissues, suggesting the possibility of the presence of a cGMP/PDE5 pathway in these tissues.
