Biological background
Structurally, MSRA is a 235-amino-acid protein of approximately 26 kilodaltons containing a thioredoxin-like catalytic domain with a conserved cysteine residue essential for redox cycling. It exists in multiple isoforms localized to cytosolic, mitochondrial, and peroxisomal compartments, ensuring broad cellular protection. The enzyme utilizes thioredoxin as an electron donor, enabling reduction of oxidized methionine residues in structural and metabolic proteins.
The MSRA antibody is widely used in oxidative stress, neurodegeneration, and aging research to study redox regulation, protein repair, and cellular stress defense. Western blot analysis detects a 26 kilodalton band corresponding to MSRA, while immunofluorescence shows strong cytoplasmic and mitochondrial staining. This antibody provides a powerful tool for analyzing antioxidant defense systems and understanding how methionine oxidation influences cellular resilience and disease processes.
Functionally, MSRA contributes to cellular longevity by maintaining the functionality of oxidatively damaged proteins, particularly in mitochondria where ROS production is high. It has been implicated in protecting against neurodegenerative disorders, cardiovascular diseases, and metabolic stress. Loss of MSRA activity accelerates protein oxidation and mitochondrial dysfunction, whereas its overexpression enhances stress tolerance and lifespan in model organisms. The MSRA antibody supports research into oxidative repair mechanisms, antioxidant therapeutics, and the molecular basis of redox regulation.
Research relevance and current trends
- Connecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).
- Considering isoforms and post-translational regulation when interpreting protein-level changes.
- Comparing results across species and model systems with matched controls.
Common research applications
- Western blotting: compare relative abundance and activation-state changes across conditions.
- Flow cytometry: quantify target-positive populations and signal shifts at single-cell resolution.
- ELISA: support antibody-based quantification in assay formats where applicable.
Interpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.
Notes for experimental interpretation
- Signal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.
- Species differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.
Antibody notes: Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.
