Anti-FZD3 antibodies are used in the immunodetection of the protein frizzled class receptor 3. In humans, the canonical protein has a reported length of 666 amino acid residues and a mass of 76.3 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the G-protein coupled receptor Fz/Smo protein family, FZD3 is a known receptor for Wnt proteins. Post-translational modifications have been described, including ubiquitination and glycosylation. Synonyms for this target antigen include frizzled-3, frizzled 3, seven transmembrane spanning receptor, frizzled family receptor 3, frizzled homolog 3, and Fz-3. FZD3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of FZD3 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
