Target Background

Function
Receptor on natural killer (NK) cells for HLA-C alleles (HLA-Cw1, HLA-Cw3 and HLA-Cw7). Inhibits the activity of NK cells thus preventing cell lysis.
Gene References into Functions
  1. These results suggest a detrimental role of HLA-A-Bw4 and HLA-C2 groups, which are associated with the development of chronic hepatitis B, and a protective role of KIR2DL3. PMID: 28211154

  3. These results show that 2DL3(+) NK cells are mediators of HIV-specific responses. Furthermore, responses of NK cell populations to iCD4 are influenced not only by NK cell education through specific KIR/HLA pairs, but also by differential HIV-mediated changes in HLA expression. PMID: 27506421
  4. Results identified three SNPs (S320F, H245Y, and H77Y) as highly deleterious in KIR2DL3 and nine SNPs (R157Q, H156Y, S63L, R157 W, F179 V, H128R, T101 M, R180C and F176I) in case of IFNL3, in coding region only with high conservation ranks highlighting the functional SNPs on phenotypic variability and disease susceptibility on HCV clearance candidate genes.

  5. gene polymorphism is associated with Crohn's disease in Spanish patients PMID: 26542067

  7. The authors have identified a deleterious effect of the KIR2DL3-HLA-C1 receptor-ligand combination on HIV clinical outcomes in a Thai cohort. PMID: 26372271
  8. Single Nucleotide Polymorphism in KIR2DL3 gene is associated with Asthma and Atopic Dermatitis. PMID: 26430804
  9. KIR2DL3 has previously been identified as important for clearance of the Hepatitis C virus after established infection,not found to be relevant to resistance to Hepatitis C infection. PMID: 24845613
  10. CD4(+) CD28(-) cells exhibited increased KIR2DS2, reduced KIR2DL3 and increased DAP12 expression in HD-ESRD compared with NDD-CKD patients. PMID: 25484131
  11. KIR2DL3 and KIR3DS1 genes could be protector genes and immuno-genetic markers for Hepatits B in the Turkish population. PMID: 24407110
  12. Higher frequency of CD158b+ natural killer cells combined with fewer activated NK cells may be associated with HCV-related chronic inflammation. PMID: 23813131

  14. Gene frequency of KIR2DL3 is lower in subjects with rheumatoid arthritis than in control. PMID: 22960345
  15. Our study indicates that the absence of the inhibitory KIR2DL3 gene is associated with an increased risk of developing multiple sclerosis in individuals carrying HLA-C1 alleles PMID: 22185807
  16. Substitutions restricted to activating KIR all reduce the avidity of KIR2DL1 and KIR2DL3, further evidence that activating KIR function often becomes subject to selective attenuation. PMID: 22772445
  17. These results suggest that natural selection has reduced the frequency of the KIR2DL3-HLA-C1 combination in malaria high-endemic population. PMID: 22412373
