Anti-HUR7 antibodies enable researchers to detect and measure the HUR7 antigen in biological samples. This target is a reported synonym of the SERPINB13 gene, which encodes serpin family B member 13. This protein is believed to play a role in the proliferation or differentiation of keratinocytes. The human version of HUR7 has a canonical amino acid length of 391 residues and a protein mass of 44.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in the vagina, tonsil, skin, esophagus, and cervix. Other names for this target antigen include HSHUR7SEQ and PI13.
