    basic FUNCTION
  • involved in HLA-E recognition (NKG2@)
  • playing a role as a receptor for the recognition of MHC class I HLA-E molecules by NK cells and some cytotoxic T-cells
  • C-type lectin required for the dimerization of the CD94/NKG2 family of receptors, which are expressed on NK cells and T cell subsets (Lieto 2003)
  • KLRD1/KLRC1 utilizes a previously undescribed endocytic mechanism coupled with an abbreviated trafficking pattern, perhaps to insure surface expression (Masilamani 2008)
  • killer lectin-like receptor on natural killer cells triggering cytotoxicity through binding of glycans on target cells including sialyl Lewis X antigen (Higai 2009)
  • peptide-selective NK cell receptor, and NK cells can be regulated by nonsignaling interactions
  • two distinct inhibitory receptor systems for MHC class I, one of which is KLRD1–KLRC1
  • in the absence of KLRC1, has a distinct specificity for HLA-E–peptide complexes
  • KLRC1 and KLRD1 operates in tandem with the polymorphic killer cell Ig-like receptors (KIR) and Ly49 systems to inhibit NK cells
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • dimerizing with KLRC1, KLRC2 or KLRC3, NKG2D, NKG2F glycoproteins in NK cell receptor (Imaizumi 2009)
  • KLRD1 forms disulfide-bonded heterodimers with the KLRC1 subunit to form an inhibitory receptor or with the KLRC2 or KLRC3 subunits to assemble a receptor complex with activating DAP12 signaling proteins
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • associating with TYROB
  • interacting with KLRK1 (KLRK1 and KLRD1 bind to heparin and sulfate-containing polysaccharides) (Higai 2009)
  • ligand for KLRK1/KLRC1, KLRC2 is leukocyte antigen (HLA)-E, which is constitutively expressed on human cells (Imaizumi 2009)
  • bind to heparin and sulfate-containing polysaccharides (this binding is interesting for natural immunity in cancer progression and metastasis)(Higai 2009)
  • covalently associate to activating or inhibitory NKG2 molecules, and their expression finely tunes cell responses
  • expression of KLRD1 and its associated KLRC1, KLRC2, KLRC3 subunits is dispensable for NK cell development, education, and many NK cell functions
  • receptor that binds HLA-E in a peptide-dependent fashion
  • KLRC3 is capable of associating with KLRD1 and TYROBP but the complex was retained intracellularly at the endoplasmic reticulum instead of being expressed on cell surfaces, and this localization was dependent on a sequence of hydrophobic AAs in the extracellular domain of KLRC3
