Killer cell immunoglobulin-like receptor, two domains, long cytoplasmic tail, 2

KIR2DL2, p58.2
Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin 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), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to 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.

Phase II Study of Haploidentical Natural Killer Cell Infusion for Treatment of Relapsed or Persistent Myeloid Malignancies Following Allogeneic Hematopoietic Cell Transplantation.
Hsu et al., New York City, United States. In Biol Blood Marrow Transplant, Feb 2016
We found a slight trend towards greater expression of KIR2DL2/2DL3/2DS2 (5% versus 28%, P = 0.03) at 14 days in patients who survived longer than 6 months from NK cell infusion (N = 4) when compared to those who died within 6 months of NK cell therapy (N=3).
Characterization of KIR intermediate promoters reveals four promoter types associated with distinct expression patterns of KIR subtypes.
Anderson et al., Frederick, United States. In Genes Immun, Jan 2016
The current study identifies ProI elements in all of the KIR genes, revealing four classes of ProI that correspond with four distinct expression phenotypes of KIR subgroups: KIR2DL2/S2/L3 that are expressed early in reconstituting NK after transplant; KIR2DL4 that is expressed by CD56-bright NK in a non-variegated manner; KIR3DL3 that is not expressed by circulating NK cells; and the remaining KIR that are expressed by subsets of CD56-dim NK.

Kurpisz et al., Wrocław, Poland. In Reprod Biol, Dec 2015
KIR2DL2 (killer immunoglobulin-like receptor two-domain long 2) and KIR2DS2 (killer immunoglobulin-like receptor two-domain short 2) genes were less frequent in patients than in control individuals (corrected p values: 0.0110 and 0.0383, respectively).

Investigation of activating and inhibitory killer cell immunoglobulin-like receptors and their putative ligands in type 1 diabetes (T1D).
ElGhazali et al., Riyadh, Saudi Arabia. In Hum Immunol, Dec 2015
KIR2DL2/2DS2-C1C1 and KIR2DL3-C1C1 were significantly associated with T1D, and KIR2DS1-C2C2 and KIR2DL1-C2C2 were significantly less frequent in T1D patients.
NK cells: tuned by peptide?
Khakoo et al., Columbus, United States. In Immunol Rev, Sep 2015
HLA-E binding non-inhibitory peptides augment inhibition at CD94:NKG2A, while HLA-C binding non-inhibitory peptides antagonize inhibition at KIR2DL2/3, implying that KIRs are specialized to respond positively to changes in peptide repertoire.

RESULTS: KIR2DL2, 2DL5a, 2DL5b and activating KIR: KIR2DS5 and 3DS1 were all protective against RA.

Ullrich et al., Oslo, Norway. In Front Immunol, 2014
Moreover, these NK cells strongly upregulated KIR2DL2/3/S2 and KIR3DL1, whereas KIR2DL1/S1 remained constant, indicating that this cell population arose from more immature NK cells instead of from activated mature ones.
Ancient Genetic Signatures of Orang Asli Revealed by Killer Immunoglobulin-Like Receptor Gene Polymorphisms.

Orang Kanaq, the smallest and the most endangered of all OA subgroups, has lost some degree of genetic variation, as shown by their relatively high frequency of the AB2 genotype (0.73) and a total absence of KIR2DL2 and KIR2DS2 genes.
