Anti-CENPU antibodies are used in the immunodetection of the protein centromere protein U. In humans, the canonical protein has a reported length of 418 amino acid residues and a mass of 47.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed at high levels in the testis, fetal liver, thymus, bone marrow and at lower levels in the lymph nodes, placenta, colon and spleen. A member of the CENP-U/AME1 protein family, CENPU is a known component of the CENPA-NAC (nucleosome-associated) complex, a complex that plays a central role in assembly of kinetochore proteins, mitotic progression and chromosome segregation. Synonyms for this target antigen include MLF1 interacting protein, centromere protein of 50 kDa, interphase centromere complex protein 24, polo-box-interacting protein 1, and KSHV latent nuclear antigen interacting protein 1. Some CENPU antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
