Uroplakin III is a transmembrane protein that is a differentiation product of urothelial cells. Uroplakin III is present on non-neoplastic mammalian urothelium at the luminal plasmalemma of superficial umbrella cells, producing complexes of 16nm particles. Anti-Uroplakin III in useful for recognizing metastatic carcinomas of urothelial origin, as many urothelial carcinomas stain positively, while several non-urothelial carcinomas do not react. Recent studies also suggest that Uroplakin III is an indicator of the malignant potential, rather than the grade of the tumor.
