Assembly of a membrane receptor complex: roles of the uroplakin II prosequence in regulating uroplakin bacterial receptor oligomerization.
The apical surface of the mammalian urothelium is almost completely covered by two-dimensional protein crystals (known as urothelial plaques) of hexagonally packed 16 nm particles consisting of two UP (uroplakin) heterodimers, i.e. UPs Ia/II and Ib/III pairs. UPs are functionally important as they contribute to the urothelial permeability barrier function, and UPIa may serve as the receptor for...
متن کاملHuman uroplakin Ib in ocular surface epithelium.
PURPOSE To investigate the expression and localization of the human gene encoding uroplakin Ib in ocular surface epithelium. METHODS The full-length cDNA of human uroplakin Ib was isolated from a cDNA library of human corneal epithelium, and the expression of uroplakin Ib in various tissues was examined by reverse transcription-polymerase chain reaction (RT-PCR). In cornea and conjunctiva, th...
متن کاملAblation of Uroplakin III Gene Results in Small Urothelial Plaques, Urothelial Leakage, and Vesicoureteral Reflux
Urothelium synthesizes a group of integral membrane proteins called uroplakins, which form two-dimensional crystals (urothelial plaques) covering >90% of the apical urothelial surface. We show that the ablation of the mouse uroplakin III (UPIII) gene leads to overexpression, defective glycosylation, and abnormal targeting of uroplakin Ib, the presumed partner of UPIII. The UPIII-depleted urothe...
متن کاملUroplakin IIIb, a urothelial differentiation marker, dimerizes with uroplakin Ib as an early step of urothelial plaque assembly
Urothelial plaques consist of four major uroplakins (Ia, Ib, II, and III) that form two-dimensional crystals covering the apical surface of urothelium, and provide unique opportunities for studying membrane protein assembly. Here, we describe a novel 35-kD urothelial plaque-associated glycoprotein that is closely related to uroplakin III: they have a similar overall type 1 transmembrane topolog...
متن کاملHigh expression level of preoperative serum Uroplakin III is associated with biologically aggressive bladder cancer.
BACKGROUND Uroplakins have been widely investigated as potential markers in patients with bladder cancer because these proteins are specific to the urothelium. However, the role of uroplakin proteins in bladder cancer remains unknown. In this study, preoperative serum levels of uroplakin III were measured in patients with urothelial carcinoma of the urinary bladder and examined for possible ass...
