Anti-CDCA2 antibodies are used in the immunodetection of the protein cell division cycle associated 2. In humans, the canonical protein has a reported length of 1023 amino acid residues and a mass of 112.7 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. CDCA2 is a reported regulator of chromosome structure during mitosis required for condensin-depleted chromosomes to retain their compact architecture through anaphase. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include protein phosphatase 1, regulatory subunit 81, recruits PP1 onto mitotic chromatin at anaphase protein, and cell division cycle-associated protein 2. CDCA2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CDCA2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
