HLA-F, a non-classical MHC molecule, is not known to present peptides. Dulberger et al. (2017) show that HLA-F contains a distinct peptide-binding groove and can present a diverse array of peptides. LIR1, however, recognized HLA-F away from bound peptide, leaving open whether peptide-HLA-F-specific T and NK receptors exist.
HLA-F 是一种非经典的 MHC 分子,目前已知它不能呈递肽。Dulberger 等人(2017 年)表明,HLA-F 含有独特的肽结合槽,能够呈递多样化的肽。然而,LIR1 识别的 HLA-F 并未结合肽,这使得是否存在肽-HLA-F 特异性 T 和 NK 受体仍不清楚。
