  • Synonym
    CD158f
  • Source
    Human KIR2DL5 / CD158f Protein, Fc Tag(KIA-H5255) is expressed from human 293 cells (HEK293). It contains AA His 22 - His 240 (Accession # Q8N109-1 ).
    Predicted N-terminus: His 22
  • Molecular Characterization
    KIR2DL5A Structure

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

    The protein has a calculated MW of 50 kDa. The protein migrates as 63-70 kDa 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 50 mM Tris,100 mM Glycine,25 mM Arg,150 mM NaCl,pH7.5 with trehalose as protectant.

  • Background
    Killer cell immunoglobulin-like receptor 2DL5(KIR2DL5), which belongs to the immunoglobulin superfamily, is an inhibitory receptor of NK cells. KIR2DL5 is encoded by two paralogous genes displaying copy number variation and allelic polymorphism-KIR2DL5A and KIR2DL5B that vary by only 2 aa in domain and 1 aa in signal peptide. KIR2DL5 and KIR2DL4 form a subfamily, which have longer cytoplasmic tails than other KIR, and each has one D0 and one D2-type Ig-like domain.
