In a study initially designed to evaluate the specific protein gene product 9.5 expression in parietal epithelial cells of Bowman's capsule, a marked positivity was also observed in the tubular and collecting duct epithelial cells. Since protein gene product 9.5 is an important enzyme in the ubiquitin system of proteolysis, and plays a regulatory role in cell cycle and proliferation, its presence in specific segments of the nephron was of considerable interest.
