motifs/domains
  • two tyrosine based inhibitory motifs (ITIM)
  • a 21-amino acid signal peptide
  • an extracellular region containing three C2-type Ig-like domains with 3 potential N-linked glycosylation sites
  • a KIR3DL interaction site seem to be largely conserved across the KIR3D family, with specificity differences mapping to a hotspot within the interaction interface
  • a 20-amino acid hydrophobic transmembrane region
  • and a 95-amino acid cytoplasmic domain
    • mono polymer dimer

    basic FUNCTION
  • inhibiting the activity of NK cells thus preventing cell lysis
  • crucial role of KIR3DL2 in microbial CpG oligodeoxynucleotide-mediated NK responses
  • three domain killer cell immunoglobulin-like receptor incorporating cytoplasmic immunoreceptor tyrosine inhibitory motifs, expressed as a disulphide-bonded dimer
  • KIR3DL2-expressing natural killer (NK) cells and IL17 secreting CD4 T cells have been implicated in the pathogenesis of ankylosing spondylitis
