  • 產品描述:

    The Recombinant Human TRAC protein is a protein encoded by recombinant DNA that was cloned in an expression vector that supported the expression of TRAC gene. This recombinant TRAC protein was expressed in the host. The expression region is 1-142aa of the Human TRAC. In the production, the expression vector contains N-terminal 6xHis tag. Every production step was performed with a strict QC system. The purity of this protein is 90%+ determined by SDS-PAGE.

    The TRAC gene encodes for the constant region of the TCR subunit and is essential for membrane expression of the TCRαβ heterodimer. In recent years, researcher revealed the important roles of TRAC in different diseases. For example, it has been found that mutation in the TCRα subunit constant gene leads to a human immunodeficiency disorder characterized by a lack of TCRαβ+ T cells. Besides, narcolepsy is strongly associated with the T-cell receptor alpha locus. Furthermore, gene rearrangements and lymphoma are partly responsible for a pathogenic TRAC Variant. Previous studies have shown that mutation in TCRα subunit constant (TRAC) leads to loss of αβ TCR on T-cell surface. Beyond this, some findings indicate that CRISPR-Cas9-mediated multiplex gene editing of TRAC, B2M, and PD-1 in CAR-T cells. The reports further adds that although these double (TRAC/B2M)- and triple (TRAC/B2M/PD-1)-negative CAR-T cells need to be further tested for their safety and efficacy in clinical studies, our results suggest that they are promising reagents for cancer therapy.

靶點詳情

  • 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.
