Biological background
EWSR1 (protein: T-cell surface glycoprotein CD4) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Integrin alpha-V/beta-3 (ITGAV:ITGB3) is a receptor for cytotactin, fibronectin, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin, vitronectin and von Willebrand factor. Integrin alpha-IIb/beta-3 (ITGA2B:ITGB3) is a receptor for fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin and vitronectin. Integrins alpha-IIb/beta-3 and alpha-V/beta-3 recognize the sequence R-G-D in a wide array of ligands. Integrin alpha- IIb/beta-3 recognizes the sequence H-H-L-G-G-G-A-K-Q-A-G-D-V in fibrinogen gamma chain. Following activation integrin alpha- IIb/beta-3 brings about platelet/platelet interaction through binding of soluble fibrinogen. This step leads to rapid platelet aggregation which physically plugs ruptured endothelial surface. Fibrinogen binding enhances SELP expression in activated platelets (By similarity). In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions. . Reported cellular localization context: Cell membrane ; Single- pass type I membrane protein . Cell projection, lamellipodium membrane . Cell junction, focal adhesion . Tissue expression notes (as provided): Isoform beta-3A and isoform beta-3C are widely expressed. Isoform beta-3A is specifically expressed in osteoblast cells; isoform beta-3C is specifically expressed in prostate and testis.
Research relevance and current trends

- 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 EWSR1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect EWSR1 expression by Western blot in cell or tissue lysates, Detect EWSR1 in FFPE tissue sections by immunohistochemistry, Localize EWSR1 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: 95 kDa; calculated MW: 87058 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
