Anti-Wnt family member 4 antibodies are used for the immunodetection of the protein encoded by the WNT4 gene. 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. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Wnt protein family, it is known to be involved with the apoptotic pathway and the Wnt signaling pathway. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include protein Wnt-4, wingless-type MMTV integration site family, member 4, and SERKAL. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 70 citations in the literature describe the use of Wnt family member 4 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
