Gene Gene information from NCBI Gene database.
Entrez ID 3551
Gene name Inhibitor of nuclear factor kappa B kinase subunit beta
Gene symbol IKBKB
Synonyms (NCBI Gene)
IKK-2IKK-betaIKK2IKKBIMD15IMD15AIMD15BNFKBIKB
Chromosome 8
Chromosome location 8p11.21
Summary The protein encoded by this gene phosphorylates the inhibitor in the inhibitor/NF-kappa-B complex, causing dissociation of the inhibitor and activation of NF-kappa-B. The encoded protein itself is found in a complex of proteins. Several transcript variant
