Description

IKBKB, also known as IKK-beta or IKK2, serves as a critical catalytic subunit of the IκB kinase complex that orchestrates NF-κB activation. This serine/threonine kinase phosphorylates inhibitory IκB proteins, triggering their degradation and enabling NF-κB transcription factors to translocate to the nucleus and drive gene expression programs central to inflammation, immunity, and cell survival. Given its pivotal role in these pathways, IKBKB has become an essential target for researchers investigating inflammatory diseases, immune regulation, and cardiovascular biology.

This recombinant monoclonal antibody, clone 5D12, offers the reproducibility and consistency that demanding experimental workflows require. Generated against a synthetic peptide derived from human IKK-beta and produced using recombinant technology in rabbit, this antibody provides sequence-defined specificity that eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived reagents. The result is reliable performance across extended research programs where experimental continuity matters.

Validation studies confirm robust detection of IKBKB in Western blot applications, with successful identification of the expected 87 kDa band across multiple human cell lines including HeLa, Jurkat, and K562 whole cell lysates. This performance across diverse cellular backgrounds demonstrates reliable target recognition in commonly used research models. The recommended working dilution range of 1:500 to 1:5000 for Western blotting provides flexibility to optimize signal intensity based on your specific experimental conditions and sample abundance.

Whether your research focuses on NF-κB signaling mechanisms, inflammatory pathway dissection, or cardiovascular disease models, this antibody delivers the specificity and consistency needed for meaningful experimental outcomes.

Target Background

Function

Serine kinase that plays an essential role in the NF-kappa-B signaling pathway which is activated by multiple stimuli such as inflammatory cytokines, bacterial or viral products, DNA damages or other cellular stresses. Acts as part of the canonical IKK complex in the conventional pathway of NF-kappa-B activation. Phosphorylates inhibitors of NF-kappa-B on 2 critical serine residues. These modifications allow polyubiquitination of the inhibitors and subsequent degradation by the proteasome. In turn, free NF-kappa-B is translocated into the nucleus and activates the transcription of hundreds of genes involved in immune response, growth control, or protection against apoptosis. In addition to the NF-kappa-B inhibitors, phosphorylates several other components of the signaling pathway including NEMO/IKBKG, NF-kappa-B subunits RELA and NFKB1, as well as IKK-related kinases TBK1 and IKBKE. IKK-related kinase phosphorylations may prevent the overproduction of inflammatory mediators since they exert a negative regulation on canonical IKKs. Phosphorylates FOXO3, mediating the TNF-dependent inactivation of this pro-apoptotic transcription factor. Also phosphorylates other substrates including NCOA3, BCL10 and IRS1. Within the nucleus, acts as an adapter protein for NFKBIA degradation in UV-induced NF-kappa-B activation. Phosphorylates RIPK1 at 'Ser-25' which represses its kinase activity and consequently prevents TNF-mediated RIPK1-dependent cell death. Phosphorylates the C-terminus of IRF5, stimulating IRF5 homodimerization and translocation into the nucleus.
