Biological background
Protein disulfide-isomerase A4 is a member of the protein disulfide-isomerase family, characterized by thioredoxin-like domains that mediate redox reactions. Research using PDIA4 antibody has shown that ERp72 interacts with a wide range of substrates, ensuring correct disulfide bond formation during protein maturation. This activity contributes to protein stability and function, making PDIA4 essential for secretory pathway homeostasis.
PDIA4 also plays a role in the unfolded protein response. Studies with PDIA4 antibody have demonstrated that its expression increases during endoplasmic reticulum stress, reflecting a need for enhanced protein folding capacity. By assisting in protein quality control, PDIA4 protects cells from accumulation of misfolded proteins and prevents activation of apoptosis pathways triggered by unresolved stress.
Beyond folding, Protein disulfide-isomerase A4 has been linked to calcium homeostasis and chaperone activity. Research using PDIA4 antibody has suggested that ERp72 participates in calcium binding and contributes to regulation of calcium dependent processes in the endoplasmic reticulum. These functions underscore the multifunctional nature of PDIA4 in cellular physiology.
Dysregulation of PDIA4 is associated with disease. Elevated expression has been observed in cancers, where increased folding capacity supports tumor cell survival under stress. Conversely, mutations or impaired function may contribute to protein misfolding disorders. Research using PDIA4 antibody has revealed roles in neurodegeneration, diabetes, and cardiovascular disease, reflecting its broad importance across pathologies.
PDIA4 antibody is widely used in western blotting, immunohistochemistry, and immunofluorescence. Western blotting detects ER localized PDIA4, immunohistochemistry highlights expression in secretory tissues, and immunofluorescence reveals endoplasmic reticulum distribution. These applications make PDIA4 antibody a valuable tool in cell biology and disease research.
By supplying validated PDIA4 antibody reagents,
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.
- Immunohistochemistry: map target signal in tissue context and compare regions/phenotypes.
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: Monoclonal antibodies provide a defined epitope recognition profile that can support consistent comparisons across experiments.
