Anti-WD Repeat Domain 46 antibodies are used in the immunodetection of the protein encoded by the WDR46 gene. In humans, the canonical protein has a reported length of 610 amino acid residues and a mass of 68.1 kDa. Its subcellular localization is in the nucleus. It is reported to be a scaffold component of the nucleolar structure. Other names for this target antigen include C6orf11, FP221, UTP7, WD repeat-containing protein 46, WD repeat-containing protein BING4, and BING4.
