Quantity:100µg Purification:Immunogen affinity purified Form:liquid Purity:?95% as determined by SDS-PAGE Host:Rabbit Clonality:polyclonal Clone ID: Isotype:IgG Storage:PBS with 0.02% sodium azide and 50% glycerol pH 7.3,-20? for 12 months(Avoid repeated freeze / thaw cycles.) Background:Tyrosine kinase that plays an essential role in regµLation of the adaptive immune response. RegµLates 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 throµgh ITAM motif at the plasma membrane. This recruitment serves to localization to the stimµLated 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 molecµLes are recruited and µLtimately 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 throµgh interaction with the E3 ubiquitin-protein ligase CBL and adapter proteins SLA and SLA2. Thus, ZAP70 regµLates both T-cell activation switch on and switch off by modµLating 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 throµgh B-cell receptor(BCR).
