Description

IKK beta (IKBKB) serves as a critical catalytic subunit of the IκB kinase complex, functioning as a central regulator of NF-κB signaling. This kinase phosphorylates inhibitory IκB proteins, triggering their degradation and enabling NF-κB transcription factors to translocate to the nucleus and activate inflammatory and survival gene programs. Given its pivotal role in immune responses, inflammation, and cell survival pathways, IKK beta represents an essential target for researchers investigating signal transduction mechanisms, cardiovascular disease, and immunological processes.

This recombinant monoclonal antibody, generated against a synthetic peptide derived from human IKK beta, offers the reproducibility and consistency that demanding experimental workflows require. As a sequence-defined reagent produced through recombinant technology, it eliminates the lot-to-lot variability that can compromise longitudinal studies and ensures reliable performance across your research timeline. The rabbit IgG format and affinity-purified preparation deliver excellent signal-to-noise characteristics across multiple detection platforms.

Validation studies demonstrate robust performance in western blotting, where the antibody detects a band at the predicted 87 kDa molecular weight in K562, MCF-7, and U251 cell lysates at dilutions ranging from 1:500 to 1:5000. Immunohistochemistry applications have been validated in paraffin-embedded human breast cancer tissue using citrate buffer antigen retrieval, while immunofluorescence staining in HeLa cells confirms utility for subcellular localization studies. This application flexibility allows you to characterize IKK beta expression and distribution using complementary techniques within a single project.

Whether you are dissecting NF-κB pathway dynamics, exploring inflammatory signaling in cancer models, or investigating cardiovascular inflammation, this antibody provides a dependable tool for advancing your research objectives.

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.
