Anti-CENPJ antibodies are used in the immunodetection of the protein centromere protein J. In humans, the canonical protein has a reported length of 1338 amino acid residues and a mass of 153 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. A member of the TCP10 protein family, CENPJ is known to play an important role in cell division and centrosome function by participating in centriole duplication. Post-translational modifications have been described, including phosphorylation. The CENPJ gene has been associated with the disease, Microcephaly. Synonyms for this target antigen include LYST-interacting protein 1, LYST-interacting protein LIP1, LYST-interacting protein LIP7, Spindle assembly abnormal 4, centrosomal P4.1-associated protein, and LAG-3-associated protein. CENPJ gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
