Recombinant human UPK3A protein
UPK3A belongs to the uroplakin-3 family. uroplakins (uP) are key components of the urothelium. They are transmembrane proteins that pass the lipid bilayer once (uPII, uPIIIa, and uPIIIb) or four times (uPIa and uPIb; both belonging to the 'tetraspanin' family) . All have large luminal/extracellular domains, but only uPIIIa and uPIIIb have significant cytoplasmic portions in their C-termini. uPK3A is a highly specific and moderately sensitive immunohistochemical marker for primary and metastatic urothelial carcinomas. Mutations in this gene may be associated with renal adysplasia Recombinant human uPK3A protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer.
