Biological background
Functionally, STRN3 antibody identifies an 837-amino-acid protein that serves as a platform for assembling PP2A catalytic and regulatory subunits along with kinases such as MST3 and GCKIII family members. STRN3 modulates dephosphorylation of signaling proteins involved in cell adhesion, polarity, and morphogenesis. Its calmodulin-binding domain enables calcium-dependent regulation of complex formation.
The STRN3 gene is located on chromosome 14q12 and is expressed in various tissues, with particularly high levels in brain and heart. STRN3 participates in diverse signaling pathways, including the Hippo pathway, where it regulates MST1/2 kinase activity and contributes to growth control and organ size regulation. Its scaffold function allows spatial coordination between kinases and phosphatases within signaling microdomains.
Pathologically, aberrant STRN3 activity has been linked to cancer progression, cardiac hypertrophy, and neuronal dysfunction. Dysregulated STRIPAK signaling disrupts phosphorylation balance and cytoskeletal remodeling. STRN3 expression changes have been observed in glioblastoma and colon carcinoma, underscoring its importance in cell growth and motility.
STRN3 antibody is suitable for western blotting, immunofluorescence, and co-immunoprecipitation to identify PP2A-associated signaling complexes.
Structurally, Striatin-3 includes an N-terminal caveolin-binding motif, coiled-coil regions for oligomerization, a calmodulin-binding site, and WD-repeat domains for protein interactions. This antibody aids studies into STRN3's role as a scaffold coordinating phosphatase and kinase communication across multiple pathways.
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.
