Anti-BOM antibodies enable researchers to detect and measure the BOM antigen in biological samples. This target is a reported synonym of the GRHL2 gene, which encodes grainyhead like transcription factor 2. This protein is known to function in brain development and eye development, among other biological roles. The human version of BOM has a canonical amino acid length of 625 residues and a protein mass of 71.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. BOM is a member of the Grh/CP2 protein family.
