These attributes help contextualize how the antibody is commonly selected (host/clonality/isotype/label) and how signals are interpreted across sample types and assay formats.

Biological background

Function: Component of the BHC complex, a corepressor complex that represses transcription of neuron-specific genes in non-neuronal cells. The BHC complex is recruited at RE1/NRSE sites by REST and acts by deacetylating and demethylating specific sites on histones, thereby acting as a chromatin modifier. In the BHC complex, it may act as a scaffold. Inhibits KDM1A-mediated demethylation of 'Lys-4' of histone H3 in vitro, suggesting a role in demethylation regulation.

Cellular localization: Nucleus.

Tissue details: Highly expressed in brain. Expressed at much lower level in other tissues.

Background: NUBP1 also known as NBP as is expressed in several tissues with the highest being in the lung and testis. NUBP1 appears to interact with actin and the cytoskeleton and is required for centrosome duplication but it is also need for proper synthesis of iron sulfur proteins and the protein also binds ATP. NUBP1 has roles in cell growth, cellular iron homeostasis, centrosome localization, iron-sulfur cluster assembly, and apolipoprotein modification. NUBP1 is localized to the cytoplasm. Interestingly too, recent research indicates that mutations in NUBP1 in mice lead defects in lung development and eye cataracts, many of which are traced back to NUBP1 role in regulating centrosome dynamics and microtubule organization.

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.
• Immunofluorescence / ICC: evaluate subcellular localization and co-localization with compartment markers.
• 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.
