ZAP-70 (Zeta-chain-associated protein kinase 70) encodes an enzyme belonging to the protein tyrosine kinase family, and it plays a role in T-cell development and lymphocyte activation. This enzyme, which is phosphorylated on tyrosine residues upon T-cell antigen receptor (TCR) stimulation, functions in the initial step of TCR-mediated signal transduction in combination with the Src family kinases, Lck and Fyn. This enzyme is also essential for thymocyte development. Mutations in this gene cause selective T-cell defect, a severe combined immunodeficiency disease characterized by a selective absence of CD8-positive T-cells. Two transcript variants that encode different isoforms have been found for this gene. Functional note: Tyrosine kinase that plays an essential role in regulation of the adaptive immune response. Regulates motility, adhesion and cytokine expression of mature T-cells, as well as thymocyte development. Contributes also to the development and activation of primary B-lymphocytes. When antigen presenting cells (APC) activate T-cell receptor (TCR), a serie of phosphorylations lead to the recruitment of ZAP70 to the doubly phosphorylated TCR component CD247\/CD3Z through ITAM motif at the plasma membrane. This recruitment serves to localization to the stimulated TCR and to relieve its autoinhibited conformation. Release of ZAP70 active conformation is further stabilized by phosphorylation mediated by LCK. Subsequently, ZAP70 phosphorylates at least 2 essential adapter proteins: LAT and LCP2. In turn, a large number of signaling molecules are recruited and ultimately lead to lymphokine production, T-cell proliferation and differentiation. Furthermore, ZAP70 controls cytoskeleton modifications, adhesion and mobility of T-lymphocytes, thus ensuring correct delivery of effectors to the APC. ZAP70 is also required for TCR-CD247\/CD3Z internalization and degradation through interaction with the E3 ubiquitin-protein ligase CBL and adapter proteins SLA and SLA2. Thus, ZAP70 regulates both T-cell activation switch on and switch off by modulating TCR expression at the T-cell surface. During thymocyte development, ZAP70 promotes survival and cell-cycle progression of developing thymocytes before positive selection (when cells are still CD4\/CD8 double negative). Additionally, ZAP70-dependent signaling pathway may also contribute to primary B-cells formation and activation through B-cell receptor (BCR). . Reported localization: Cytoplasm . Cell membrane ; Peripheral membrane protein . In quiescent T-lymphocytes, it is cytoplasmic. Upon TCR activation, it is recruited at the plasma membrane by interacting with CD247\/CD3Z. Colocalizes together with RHOH in the immunological synapse. RHOH is required for its proper localization to the cell membrane and cytoskeleton fractions in the thymocytes (By similarity). . Expression\/tissue context: Expressed in T- and natural killer cells. Also present in early thymocytes and pro\/pre B-cells. .\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eAdaptive Immunity: Researchers commonly examine how ZAP70 (Tyrosine-protein kinase ZAP-70) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eCell Type Markers: Researchers commonly examine how ZAP70 (Tyrosine-protein kinase ZAP-70) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eImmunology: Researchers commonly examine how ZAP70 (Tyrosine-protein kinase ZAP-70) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: compare relative ZAP70 (Tyrosine-protein kinase ZAP-70) levels across conditions; band patterns may reflect isoforms and processing.\u003c\/li\u003e\n\u003cli\u003eIHC\/IHC-F: assess spatial distribution of ZAP70 (Tyrosine-protein kinase ZAP-70) across tissue regions and cell types using matched controls.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSpecificity notes:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCross-reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD\/KO samples when available.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt entry for P43403: https:\/\/www.uniprot.org\/uniprotkb\/P43403\/entry - PubMed search (ZAP70): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=ZAP70 - NCBI Gene search (ZAP70): https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=ZAP70 - Antibody validation concepts (NIH): https:\/\/www.nih.gov\/research-training\/rigor-reproducibility --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53066839589229,"sku":"PB9968","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53067202986349,"sku":"PB9968-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53067203019117,"sku":"PB9968-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53067203051885,"sku":"PB9968-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53067203084653,"sku":"PB9968-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53067203117421,"sku":"PB9968-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53067203150189,"sku":"PB9968-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53067203182957,"sku":"PB9968-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53067203215725,"sku":"PB9968-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53067203248493,"sku":"PB9968-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53067203281261,"sku":"PB9968-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53067203314029,"sku":"PB9968-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/pb9968-zap70-primary-antibodies-wb-testing-1.jpg?v=1772608229","url":"https:\/\/www.ebiohippo.com\/products\/anti-zap70-antibody-picoband-bha21000867","provider":"BioHippo","version":"1.0","type":"link"}
