Biological background
CTSS (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Weakly binds calcium but binds zinc very tightly- distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites. May mediate calcium-dependent regulation on many physiological processes by interacting with other proteins, such as TPR-containing proteins, and modulating their activity. . Reported cellular localization context: Cytoplasm. Tissue expression notes (as provided): Highly prevalent in heart. Also found in lesser quantities in skeletal muscle and brain.
Research relevance and current trends
- Research context keywords from the source record include: Adaptive Immunity,Cell Biology,Cell Type Markers,Immunology,Non-CD,Proteolysis/Ubiquitin,Proteolytic Enzymes.
- 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.
- Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
Workflow ideas (metafield): Validate CTSS antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect CTSS expression by Western blot in cell or tissue lysates, Detect CTSS in FFPE tissue sections by immunohistochemistry, Localize CTSS by immunofluorescence/immunocytochemistry in cultured cells
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: 120 kDa, 140 kDa; calculated MW: 10546 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
