Description

General description

The gene NFKBIA (nuclear factor of κ light polypeptide gene enhancer B-cells inhibitor-α) encodes the α member of the NF-κ-B inhibitor family IκB, which also consists of IκBβ and IκBε. NFKBIA is also referred to as IκBα. It is the strongest inhibitor of nuclear NF-κB activity among these members. Specific phosphorylation of the inhibitor IκBα at Ser32 and Ser36, its ubiubiquitination and subsequent proteolytic degradation is necessary for the activation of NF-κ-B. It is localized to the cytosol, where it retains NF-κB. Polymorphism in this gene is linked to recurrent acute rejections in liver transplant recipients. Mutations in this gene have been linked to autosomal dominant anhidrotic ectodermal dysplasia and T cell immunodeficiency. The gene NFKBIA is mapped to human chromosome 14q13.

Immunogen

synthetic peptide corresponding to the C-terminus of human IκBα (amino acids 297-317 with N-terminally added lysine) conjugated to KLH.

Application

Anti-IκBα antibody produced in rabbit has been used in western blotting.
