Anti-uroplakin 3B like 2 antibodies are used for the immunodetection of the protein encoded by the UPK3BL2 gene. In humans, the canonical protein has a reported length of 263 amino acid residues and a mass of 28.4 kDa. Its subcellular localization is in the membrane. It is a member of the Uroplakin-3 protein family. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include uroplakin-3b-like protein 2. Gene orthologs have been identified in the mouse and chimpanzee species.
