  • Synonym
    IL-23 R,IL-23 Receptor
  • Source
    Human IL-23 R, Fc Tag(ILR-H5254) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Gly 355 (Accession # Q5VWK5-1).
    Predicted N-terminus: Gly 24
  • Molecular Characterization
    IL-23R Structure

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 64.5 kDa. The protein migrates as 90-100 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

  • Background
    Interleukin 23 receptor (IL-23R) is a type I cytokine receptor, and IL-23R pairs with the receptor molecule IL12RB1/IL12Rbeta1, and both are required for IL23A signaling. Also, IL-23R associates constitutively with Janus kinase 2 (JAK2), and binds to transcription activator STAT3 in a ligand-dependent manner. Furthermore, IL-23R mediates T-cells, NK cells and possibly certain macrophage/myeloid cells stimulation probably through activation of the Jak-Stat signaling cascade. As for IL-23, it may be responsible for autoimmune inflammatory diseases and be important for tumorigenesis.
