Biological background
CTNNA3 (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): RNA-binding protein which binds to intronic polypyrimidine tracts and mediates negative regulation of exons splicing. May antagonize in a tissue-specific manner the ability of NOVA1 to activate exon selection. In addition to its function in pre-mRNA splicing, plays also a role in the regulation of translation. Isoform 5 has a reduced affinity for RNA. . Reported cellular localization context: Nucleus . Tissue expression notes (as provided): Mainly expressed in brain although also detected in other tissues like heart and skeletal muscle. Isoform 1 and isoform 2 are specifically expressed in neuronal tissues. Isoform 3 and isoform 4 are expressed in non-neuronal tissues. Isoform 5 and isoform 6 are truncated forms expressed in non- neuronal tissues. .
Research relevance and current trends
- Research context keywords from the source record include: Amino Acid Metabolism,Cancer,Cancer Metabolism,Carbohydrate Metabolism,Energy Metabolism,Energy Transfer Pathways,Metabolic Signaling Pathway,Metabolic Signaling Pathways,Metabolism,Metabolism Of Carbohydrates,Pathways and Processes,Signal Transduction.
- Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
- Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.
Common research applications
- Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
- Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
- Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.
Workflow ideas (metafield): Validate CTNNA3 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect CTNNA3 expression by Western blot in cell or tissue lysates, Detect CTNNA3 in FFPE tissue sections by immunohistochemistry, Enrich CTNNA3 by immunoprecipitation from lysates for downstream analysis
Notes for experimental interpretation
- Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
- Apparent molecular weight may vary by sample type and processing (observed MW: 100 kDa; calculated MW: 57491 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
