When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. Upon TCR engagement, these motifs become phosphorylated by Src family protein tyrosine kinases LCK and FYN, resulting in the activation of downstream signaling pathways. In addition of this role of signal transduction in T-cell activation, CD3E plays an essential role in correct T-cell development (PubMed:19956738, PubMed:24899501). Participates also in internalization and cell surface down-regulation of TCR-CD3 complexes via endocytosis sequences present in CD3E cytosolic region.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExpression and localization notes:\u003c\/strong\u003e cellular localization: alpha-beta T cell receptor complex; external side of plasma membrane; immunological synapse; cell body; cell-cell junction; dendritic spine; integral component of membrane.\u003c\/p\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting (WB):\u003c\/strong\u003e Compare TJP2 levels across samples and conditions using appropriate loading and biological controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e Evaluate spatial distribution of TJP2 in tissue sections, considering fixation and antigen retrieval effects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence \/ ICC:\u003c\/strong\u003e Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e Quantify TJP2-positive populations in single-cell suspensions with appropriate gating and controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAccount for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.\u003c\/li\u003e \u003cli\u003eUse positive\/negative biological controls where possible (e.g., known-expressing cells\/tissues, knockdown\/knockout models) and include appropriate secondary-only\/isotype controls for imaging workflows.\u003c\/li\u003e \u003c\/ul\u003e\u003ch2\u003eAdditional product notes (from provided fields)\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackground:\u003c\/strong\u003e TJP2 (Tight Junction Protein 2), also known as Zona Occludens 2 or ZO2 is a protein that in humans is encoded by the TJP2 gene. Tight junction proteins (TJPs) belong to a family of membrane-associated guanylate kinase (MAGUK) homologs that are involved in the organization of epithelial and endothelial intercellular junctions. Duclos et al. (1994) mapped the TJP2 gene telomeric to the Friedreich ataxia critical region on chromosome 9q13-q21. TJP2 lies about 70 kb centromeric to the X123 gene and is transcribed in the centromere-to-telomere ion. Using in vitro assays and immunoprecipitation studies, Itoh et al. (1999) showed that the mouse Tjp1, Tjp2, and Tjp3 PDZ1 domains interacted with the C-terminal cytoplasmic domains of Cldn1 through Cldn8. In the mouse inner ear, Walsh et al. (2010) found that Tjp2 expression decreased rapidly between E16.5 and age 1 week to a level in adult mice that was approximately 50% of the level at birth (P0).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCellular localization:\u003c\/strong\u003e alpha-beta T cell receptor complex; external side of plasma membrane; immunological synapse; cell body; cell-cell junction; dendritic spine; integral component of membrane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResearch category:\u003c\/strong\u003e Cardiovascular,Chemokines,Immunology,Innate Immunity,Platelets\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt entry for Q9UDY2: https:\/\/www.uniprot.org\/uniprot\/Q9UDY2 - Ensembl search (TJP2): https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=TJP2 - Human Protein Atlas search (TJP2): https:\/\/www.proteinatlas.org\/search\/TJP2 - PubMed search (TJP2): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=TJP2 --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53067741036909,"sku":"A02774-1","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53068205523309,"sku":"A02774-1-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53068205556077,"sku":"A02774-1-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53068205588845,"sku":"A02774-1-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53068205621613,"sku":"A02774-1-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53068205654381,"sku":"A02774-1-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53068205687149,"sku":"A02774-1-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53068205719917,"sku":"A02774-1-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53068205752685,"sku":"A02774-1-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53068205785453,"sku":"A02774-1-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53068205818221,"sku":"A02774-1-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53068205850989,"sku":"A02774-1-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/a02774-1-tjp2-primary-antibodies-wb-testing-1.jpg?v=1772609784","url":"https:\/\/www.ebiohippo.com\/products\/anti-tjp2-zo2-antibody-picoband-bha21003270","provider":"BioHippo","version":"1.0","type":"link"}
