- Listed applications: WB, FACS, Direct ELISA (refer to on-page specifications for application-specific guidance).
Biological background
Protein phosphatase 1 regulatory subunit 15A also known as growth arrest and DNA damage-inducible protein GADD34 is a protein that in humans is encoded by the PPP1R15A gene. Enables protein phosphatase binding activity and protein phosphatase regulator activity. Involved in several processes, including peptidyl-serine dephosphorylation; regulation of gene expression; and regulation of protein modification process. Acts upstream of or within endoplasmic reticulum unfolded protein response. Predicted to be located in several cellular components, including Golgi apparatus; cytosol; and mitochondrion. Predicted to be part of protein phosphatase type 1 complex. Predicted to be active in endoplasmic reticulum. Is expressed in several structures, including central nervous system; genitourinary system; gut; hemolymphoid system gland; and liver. Used to study thalassemia. Orthologous to human PPP1R15A (protein phosphatase 1 regulatory subunit 15A).
Research relevance and current trends
- Comparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).
- Subcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.
- Integration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.
Common research applications
- Western blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Flow cytometry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- ELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
Interpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.
Notes for experimental interpretation
- Isoforms and PTMs: many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands/signals accordingly.
- Epitope context: binding can depend on protein conformation and sample processing; region information in the title/immunogen can help anticipate what may be detected.
- Species differences: predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.
- Control concepts: include negative controls (no-primary/isotype), and where possible genetic controls (KO/KD) or independent antibodies to strengthen conclusions.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
