Anti-M18BP1 antibodies are used in antigen-specific immunodetection in biological samples. The target M18BP1 is a known alias name of the protein MIS18 binding protein 1, encoded by the MIS18BP1 gene in humans. This 1132-amino acid residue protein is known to be required for recruitment of CENPA to centromeres and normal chromosome segregation during mitosis. It is localized to the nucleus of the cell. It is reported to be widely expressed in many tissue types.
