Biological background

Function: Regulatory subunit of the IKK core complex which phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. Its binding to scaffolding polyubiquitin seems to play a role in IKK activation by multiple signaling receptor pathways. However, the specific type of polyubiquitin recognized upon cell stimulation (either 'Lys-63'- linked or linear polyubiquitin) and its functional importance is reported conflictingly. Also considered to be a mediator for TAX activation of NF-kappa-B. Could be implicated in NF-kappa-B- mediated protection from cytokine toxicity. Essential for viral activation of IRF3. Involved in TLR3- and IFIH1-mediated antiviral innate response; this function requires 'Lys-27'-linked polyubiquitination. .

Cellular localization: Cytoplasm . Nucleus . Sumoylated NEMO accumulates in the nucleus in response to genotoxic stress.

Tissue details: Heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.

Background: Delta-like 4 is a protein that in humans is encoded by the DLL4 gene. It is mapped to 15q15.1. This gene is a homolog of the Drosophila delta gene. The delta gene family encodes Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. And this gene plays an important role in promoting Th17 effector activity during mycobacterial challenge.

Cross reactivity: No cross-reactivity with other proteins.

Research relevance and current trends

• Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
• Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
• Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.

Common research applications

• Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
• Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
• Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.

Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.

Notes for experimental interpretation

• Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
• Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
• Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.

For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
