Summary: This gene encodes one of the proteins of the highly conserved urothelium-specific integral membrane proteins of the asymmetric unit membrane which forms urothelium apical plaques in mammals. The asymmetric unit membrane is believed to strengthen the urothelium by preventing cell rupture during bladder distention. The encoded protein is expressed in the peripheral blood of bladder cancer patients with transitional cell carcinomas.[provided by RefSeq, Sep 2009]
Expression: Biased expression in urinary bladder (RPKM 26.3) and fat (RPKM 1.3) See more

Title: Expression of uroplakin II and GATA-3 in bladder cancer mimickers: caveats in the use of a limited panel to determine cell of origin in bladder lesions.
Uroplakin II was immunopositive in 53% and 60% of urothelial carcinomas (UC) of the bladder and the ureter, respectively.
Title: Diagnostic Utility of Prostein, Uroplakin II and SATB2 for Diagnosing Carcinoma of Unknown Primary Origin: A Systematic Immunohistochemical Profiling.
These results suggest that whereas GATA-3 and uroplakin II may be most useful in the diagnosis of urothelial carcinoma metastasis, p40 may be additionally suited as a prognostic marker.
Title: A combination of p40, GATA-3 and uroplakin II shows utility in the diagnosis and prognosis of muscle-invasive urothelial carcinoma.
UPII, GATA3, and p40, when used in combination, are highly sensitive in the differential diagnosis of invasive urothelial carcinoma.
Title: Uroplakin II (UPII), GATA3, and p40 are Highly Sensitive Markers for the Differential Diagnosis of Invasive Urothelial Carcinoma.
UPII was highly specific/moderately sensitive for urothelial carcinoma. May be a potentially useful marker to identify urothelial lineage and help distinguish UC from prostate cancer or, in conjunction with GATA3, from metastatic breast cancer.
Title: Utility of uroplakin II expression as a marker of urothelial carcinoma.
UPII demonstrates a significantly higher sensitivity than UPIII in conventional and variant urothelial carcinomas
Title: Uroplakin II is a more sensitive immunohistochemical marker than uroplakin III in urothelial carcinoma and its variants.
Uroplakin II antibody BC21 demonstrated superior sensitivity and specificity in urothelial carcinoma, compared with uroplakin III, suggesting an advantage in differential diagnosis of urothelial carcinoma and in the detection of tumors of unknown origin.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
