Anti-FZ7 antibodies enable researchers to detect and measure the FZ7 antigen in biological samples. This target is a reported synonym of the FZD7 gene, which encodes frizzled class receptor 7. This protein is known to function in the Wnt signaling pathway and the regulation of cell differentiation, among other biological roles. The human version of FZ7 has a canonical amino acid length of 574 residues and a protein mass of 63.6 kilodaltons. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. Other names for this target antigen include FzE3, frizzled-7, and Frizzled, drosophila, homolog of, 7.
