Biological background
STAG2 (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Mitochondrial membrane ATP synthase (F (1)F (0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F (1) - containing the extramembraneous catalytic core, and F (0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F (1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Subunits alpha and beta form the catalytic core in F (1). Rotation of the central stalk against the surrounding alpha (3)beta (3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits. Subunit alpha does not bear the catalytic high-affinity ATP-binding sites (By similarity). . Reported cellular localization context: Cytoplasm . Tissue expression notes (as provided): Fetal lung, heart, liver, gut and kidney. Expressed at higher levels in the fetal brain, retina and spinal cord. .
Research relevance and current trends
- Research context keywords from the source record include: Cell Biology,Cell Cycle,Cell Division,Chromosome Structure,Epigenetics and Nuclear Signaling.
- 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.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
Workflow ideas (metafield): Validate STAG2 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect STAG2 expression by Western blot in cell or tissue lysates, Detect STAG2 in FFPE tissue sections by immunohistochemistry, Localize STAG2 by immunofluorescence/immunocytochemistry in cultured cells, Quantify STAG2-positive cells by flow cytometry in single-cell suspensions
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: 66 kDa; calculated MW: 94331 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
