Killer cell immunoglobulin-like receptors (KIRs), also known as Killer-cell Inhibitory Receptors, are single pass type I transmembrane glycoproteins that belong to the immunoglobulin superfamily (IgSF).  The KIR genes are highly homologous and polymorphic.  Most of them are found in a cluster on chromosome 19q13.4 within the leukocyte receptor complex (LRC). KIRs are expressed on natural killer (NK) cells and subsets of T cells. KIR proteins are composed of 2 or 3 extracellular Ig domains, a transmembrane region and cytoplasmic tail which can in turn be short or long. The KIR proteins are thus classified by the number of Ig-domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM).  In contrast KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response. KIR3DL subgroup proteins, including KIR3DL1 (CD158E), KIR3DL2 (CD158K), and KIR3DL3 (CD158Z), are receptors on NK cells for HLA Bw4 alleles and inhibit the activity of NK cells thus preventing cell lysis.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CGGGAAGCAATAGCATGATA-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
