Anti-WNT4 antibodies are used in the immunodetection of the protein Wnt family member 4. In humans, the canonical protein has a reported length of 351 amino acid residues and a mass of 39.1 kDa. Its subcellular localization is in the extracellular matrix and is secreted. Up to 2 different isoforms have been reported for this protein. A member of the Wnt protein family, WNT4 is known to be involved with the apoptotic pathway and the Wnt signaling pathway. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include protein Wnt-4, wingless-type MMTV integration site family, member 4, and SERKAL. WNT4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 70 citations in the literature describe the use of WNT4 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
