Anti-WIZ zinc finger antibodies are used for the immunodetection of the protein encoded by the WIZ gene. In humans, the canonical protein has a reported length of 1651 amino acid residues and a mass of 178.7 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 4 different isoforms for this protein. A member of the Krueppel C2H2-type zinc-finger protein family, it is believed to link EHMT1 and EHMT2 histone methyltransferases to the CTBP corepressor machinery. Other names for this target antigen include widely interspaced zinc finger motifs, widely-interspaced zinc finger-containing protein, zinc finger protein 803, and protein Wiz. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
