Anti-MAD3 antibodies are protein reagents that detect specific antigens. The MAD3 antigen is another term for the human protein NFKB inhibitor alpha, encoded by the NFKBIA gene. The protein is reported to inhibit the activity of dimeric NF-kappa-B/REL complexes by trapping REL dimers in the cytoplasm through masking of their nuclear localization signals. Canonically, it has an amino acid length of 317 residues and a mass of 35.6 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm and it is widely expressed in many tissue types. The MAD3 protein is a member of the NF-kappa-B inhibitor protein family. Other alias names for MAD3 include EDAID2, IKBA, and MAD-3. Western Blot is a widely used application for the MAD3 antibodies listed below. In addition, ELISA is also a common application.
