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: Involved in cellular response to oxidative stress.
Cellular localization: Secreted.
Tissue details: Detected in liver, skeletal muscle, kidney, pancreas, spleen, thyroid, testis, ovary, small intestine and colon.
Background: Using mouse Trax as bait in a yeast 2-hybrid screen, Bray et al. (2002) cloned Tsnaxip1 from a mouse testis cDNA library. The deduced protein contains 709 amino acids and has a coiled-coil structure. Mouse Tsnaxip1 shares 74% homology with the predicted human protein. Northern blot analysis of mouse tissues detected a 2.8-kb transcript only in testis. Northern blot analysis of Tsnaxip1 in developing germ cells indicated predominantly postmeiotic expression. Fluorescence-tagged Tsnaxip1 transfected into mouse fibroblasts showed a cytoplasmic distribution and concentrated staining around the nucleus. Predicted to be involved in cell differentiation and spermatogenesis. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in cytoplasm
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.
