Anti-CC2D1B antibodies are used in the immunodetection of the protein coiled-coil and C2 domain containing 1B. In humans, the canonical protein has a reported length of 858 amino acid residues and a mass of 94.2 kDa. Its subcellular localization is in the nucleus. Up to 5 different isoforms have been reported for this protein. It is reported to be widely expressed in the brain and peripheral tissues. A member of the CC2D1 protein family, CC2D1B is reported to be a transcription factor that binds specifically to the DRE (dual repressor element) and represses HTR1A gene transcription in neuronal cells. Synonyms for this target antigen include FRE under dual repression-binding protein 2, five prime repressor element under dual repression-binding protein 2, freud-2, and coiled-coil and C2 domain-containing protein 1B. CC2D1B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CC2D1B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
