|Other Names||NF-kappa-B inhibitor beta, NF-kappa-BIB, I-kappa-B-beta, IkB-B, IkB-beta, IkappaBbeta, Thyroid receptor-interacting protein 9, TR-interacting protein 9, TRIP-9, NFKBIB, IKBB, TRIP9|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP13780b was selected from the C-term region of NFKBIB. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Inhibits NF-kappa-B by complexing with and trapping it in the cytoplasm. However, the unphosphorylated form resynthesized after cell stimulation is able to bind NF-kappa-B allowing its transport to the nucleus and protecting it to further NFKBIA- dependent inactivation. Association with inhibitor kappa B- interacting NKIRAS1 and NKIRAS2 prevent its phosphorylation rendering it more resistant to degradation, explaining its slower degradation.|
|Cellular Location||Cytoplasm. Nucleus|
|Tissue Location||Expressed in all tissues examined.|

NFKB1 (MIM 164011) or NFKB2 (MIM 164012) is bound to REL(MIM 164910), RELA (MIM 164014), or RELB (MIM 604758) to form theNFKB complex. The NFKB complex is inhibited by I-kappa-B proteins(NFKBIA, MIM 164008, or NFKBIB), which inactivate NF-kappa-B bytrapping it in the cytoplasm. Phosphorylation of serine residues onthe I-kappa-B proteins by kinases (IKBKA, MIM 600664 or IKBKB, MIM603258) marks them for destruction via the ubiquitination pathway,thereby allowing activation of the NF-kappa-B complex. ActivatedNFKB complex translocates into the nucleus and binds DNA atkappa-B-binding motifs such as 5-prime GGGRNNYYCC 3-prime or5-prime HGGARNYYCC 3-prime (where H is A, C, or T; R is an A or Gpurine; and Y is a C or T pyrimidine).
