  • 产品描述：

    The human NKG2-D type II integral membrane protein or KLRK1 is a costimulatory receptor expressed in Natural Killers and CD8+ T-cells. KLRK1 participates in the immunosurveillance of tumor and virus-infected cells and mediates the activation of T-cell receptors in CD8+ cells, causing the amplification of the T-cell-mediated adaptative immune response. This target protein KLRK1 also modulates natural immunity by activating the NK cell cytotoxic activity. It’s activated by the interaction of stress-induced ligands presented on the surface by the MHC class I binding proteins. This recombinant product is the 78-216aa region of the KLRK1 protein, which is expressed in mammalian cells and fused on the C-terminus with an Fc tag. It has a final molecular weight of 43.6 kDa. This product has a purity higher than 93%, as measure by SDS-PAGE. The affinity constant of this protein against ULBP1 was 2.27 nM as detected by LSPR, and the EC50 was 222.4-276.0 ng/ml, as determined by ELISA binding assay. The protein can be used in immunity modulation and immunosuppression studies on cancer and viral diseases. The final product has low levels of endotoxin, with less than 1.0 EU/µg as determined by the LAL method.

靶点详情

  • 功能：
    Functions as an activating and costimulatory receptor involved in immunosurveillance upon binding to various cellular stress-inducible ligands displayed at the surface of autologous tumor cells and virus-infected cells. Provides both stimulatory and costimulatory innate immune responses on activated killer (NK) cells, leading to cytotoxic activity. Acts as a costimulatory receptor for T-cell receptor (TCR) in CD8(+) T-cell-mediated adaptive immune responses by amplifying T-cell activation. Stimulates perforin-mediated elimination of ligand-expressing tumor cells. Signaling involves calcium influx, culminating in the expression of TNF-alpha. Participates in NK cell-mediated bone marrow graft rejection. May play a regulatory role in differentiation and survival of NK cells. Binds to ligands belonging to various subfamilies of MHC class I-related glycoproteins including MICA, MICB, RAET1E, RAET1G, RAET1L/ULBP6, ULBP1, ULBP2, ULBP3 (ULBP2>ULBP1>ULBP3) and ULBP4.
  • 亚细胞定位：
    Cell membrane; Single-pass type II membrane protein. Note=Colocalized with HCST on the cell surface.
  • 组织特异性：
    Expressed in natural killer (NK) cells, CD8(+) alpha-beta and gamma-delta T-cells. Expressed on essentially all CD56+CD3- NK cells from freshly isolated PBMC. Expressed in interferon-producing killer dendritic cells (IKDCs).
