  • Immunofluorescence staining of Hela cells with CSB-PA335552LA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

Non-classical major histocompatibility class Ib molecule postulated to play a role in immune surveillance, immune tolerance and inflammation. Functions in two forms, as a heterotrimeric complex with B2M/beta-2 microglobulin and a peptide (peptide-bound HLA-F-B2M) and as an open conformer (OC) devoid of peptide and B2M (peptide-free OC). In complex with B2M, presents non-canonical self-peptides carrying post-translational modifications, particularly phosphorylated self-peptides. Peptide-bound HLA-F-B2M acts as a ligand for LILRB1 inhibitory receptor, a major player in maternal-fetal tolerance. Peptide-free OC acts as a ligand for KIR3DS1 and KIR3DL2 receptors. Upon interaction with activating KIR3DS1 receptor on NK cells, triggers NK cell degranulation and anti-viral cytokine production. Through interaction with KIR3DL2 receptor, inhibits NK and T cell effector functions. May interact with other MHC class I OCs to cross-present exogenous viral, tumor or minor histompatibility antigens to cytotoxic CD8+ T cells, triggering effector and memory responses. May play a role in inflammatory responses in the peripheral nervous system. Through interaction with KIR3DL2, may protect motor neurons from astrocyte-induced toxicity.
Gene References into Functions
  1. interactions between KIR3DS1 and HLA-F contribute to NK cell-mediated control of HCV. PMID: 30031767
  2. the results of this study provide a blueprint of the molecular details of HLA-F, which will inform future exploration of its roles in human health and allow for the development of additional, targeted therapeutics PMID: 28636952
  3. this study established HLA-F as a ligand of KIR3DS1 and have demonstrated cell-context-dependent expression of HLA-F that might explain the widespread influence of KIR3DS1 in human disease, including delayed progression of disease caused by human immunodeficiency virus type 1 PMID: 27455421
  4. Two eSNPs were associated with fecundability at a FDR of 5%; both were in the HLA region and were eQTLs for the TAP2 gene (P = 1.3x10-4) and the HLA-F gene (P = 4.0x10-4), respectively. PMID: 27447835
  5. provides substantial evidence that the rs7903146 variant is significantly associated with the risk of diabetic retinopathy in Caucasian populations PMID: 26332651
  6. Overexpression of a single MHCI molecule, HLA-F, protects human MNs from ALS astrocyte-mediated toxicity, whereas knockdown of its receptor, the killer cell immunoglobulin-like receptor KIR3DL2, on human astrocytes results in enhanced motor neurons death PMID: 26928464
  7. This is the first study regarding HLA-F polymorphisms in a Euro-Brazilian population contributing to the Southern Brazilian genetic characterization. PMID: 25413105
  8. The effect of Japanese encephalitis virus and TNF-alpha exposure on NFkappaB-mediated induction of HLA-F is reported. PMID: 25461528
  9. A previously unrecognized model of Ag cross-presentation mediated by HLA-F & MHC-I open conformers on activated lymphocytes & monocytes may significantly contribute to the regulation of immune system functions & the immune defense. PMID: 23851683
  10. expression in gastric cancer lesion was unrelated to patient prognosis PMID: 23542057
  11. HLA-F and MHC class I open conformers are ligands for NK cell Ig-like receptors. PMID: 24018270
  12. Upregulated HLA-F expression (p = 0.026) and downregulated HLA I expression (p = 0.013) could be an independent unfavorable prognostic factor. PMID: 22544725
  13. surface marker on activated lymphocytes PMID: 20865824
  14. These data suggest that HLA-F is expressed independently of peptide and that a physical interaction specific to MHC-I HC plays a role in the function of MHC-I HC expression in activated lymphocytes. PMID: 20483783
  15. This is the first example of placental HLA-F expression--primarily in trophoblasts that have invaded the maternal decidua--in the same cells that simultaneously express the other two nonclassical class I antigens HLA-E and HLA-G. PMID: 12874228
  16. HLA-F surface expression on B cell and monocyte cell lines correlates with the presence of a limited amount of endoglycosidase H (Endo H)-resistant HLA-F; however, clearly not all surface-expressed HLA-F is fully glycosylated. PMID: 14607927
  17. HLA-F is entirely dependent on its cytoplasmic tail for export from the endoplasmic reticulum. PMID: 16709803
  18. the role of NKG2D and 2B4 is not focussed on trophoblast recognition in normal pregnancy, but is more likely involved in cross-talk among maternal cells of the placental bed PMID: 18658158
