RBAK ELISA kits are immunoassay tools for the measurement of the protein RB associated KRAB zinc finger, which is encoded by the RBAK gene in humans. Functionally, this protein is believed to repress E2F-dependent transcription. The canonical protein structure is reported to have an amino acid length of 714 residues, a mass of 83 kDa, and is a member of the Krueppel C2H2-type zinc-finger protein family. It is known to be localized in the nucleus and is reported to be expressed in bone, brain, heart, kidney, liver, lung, pancreas and placenta. As many as 2 protein isoforms have been reported. Other alias names for this target include RB-associated KRAB repressor, zinc finger protein 769, and RB-associated KRAB zinc finger protein.
