Anti-BarH like homeobox 1 antibodies are used in the immunodetection of the protein encoded by the BARHL1 gene. In humans, the canonical protein has a reported length of 327 amino acid residues and a mass of 35.1 kDa. Its subcellular localization is in the nucleus. A member of the BAR homeobox protein family, it is known to be involved with the regulation of transcription. Other names for this target antigen include barH-like 1 homeobox protein.
