  • 产品描述：

    Intact human T cell receptor alpha constant (TRAC) cDNA (1-142aa) with an N-terminal 6xHis-tag was expressed in the yeast. The forming protein is the recombinant full-length human TRAC protein. The purity of this protein is greater than 90% determined by SDS-PAGE. Under reducing conditions, the gel showed a molecular weight band of about 16 kDa. This recombinant TRAC protein can be used as the immunogen for antibody synthesis. Besides, it also may be applied in the studies of TRAC-related immunology.

    The extracellular region of αβ T cell receptors (TCRs) is made up of an α chain and a β chain, each containing Ig-like variable and constant domains. TRAC, the TCR Cα domain, is significant in differing from the classical IgC1 domain. Substantial evidence indicated that TRAC interfaces with CD3. Mutagenesis has demonstrated that the interactions of CD3δɛ and CD3γɛ subunits with the TcR Cα and Cβ domains, respectively, contribute to the stability and function of the TCR–CD3 signaling complex. Gijs I. van Boxel etc. concluded that the TCR Cα domain can also adopt two very different stable conformations, a fundamental property that is potentially central to TCR function and that the TCR Cα domain may facilitate the "β-strand slippage."

  • 功能：
    Constant region of T cell receptor (TR) alpha chain. Alpha-beta T cell receptors are antigen specific receptors which are essential to the immune response and are present on the cell surface of T lymphocytes. Recognize peptide-major histocompatibility (MH) (pMH) complexes that are displayed by antigen presenting cells (APC), a prerequisite for efficient T cell adaptive immunity against pathogens. Binding of alpha-beta TR to pMH complex initiates TR-CD3 clustering on the cell surface and intracellular activation of LCK that phosphorylates the ITAM motifs of CD3G, CD3D, CD3E and CD247 enabling the recruitment of ZAP70. In turn, ZAP70 phosphorylates LAT, which recruits numerous signaling molecules to form the LAT signalosome. The LAT signalosome propagates signal branching to three major signaling pathways, the calcium, the mitogen-activated protein kinase (MAPK) kinase and the nuclear factor NF-kappa-B (NF-kB) pathways, leading to the mobilization of transcription factors that are critical for gene expression and essential for T cell growth and differentiation. The T cell repertoire is generated in the thymus, by V-(D)-J rearrangement. This repertoire is then shaped by intrathymic selection events to generate a peripheral T cell pool of self-MH restricted, non-autoaggressive T cells. Post-thymic interaction of alpha-beta TR with the pMH complexes shapes TR structural and functional avidity.
