Anti-RBAK antibodies are used in the immunodetection of the protein RB associated KRAB zinc finger. In humans, the canonical protein has a reported length of 714 amino acid residues and a mass of 83 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in bone, brain, heart, kidney, liver, lung, pancreas and placenta. A member of the Krueppel C2H2-type zinc-finger protein family, RBAK is believed to repress E2F-dependent transcription. Synonyms for this target antigen include RB-associated KRAB repressor, zinc finger protein 769, and RB-associated KRAB zinc finger protein. RBAK gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is a widely used application for the RBAK antibodies listed below. In addition, ELISA is also a common application.
