  • 功能:
    Receptor on natural killer (NK) cells and T cells for MHC class I molecules. Upon binding of peptide-free HLA-F open conformer, negatively regulates NK and T cell effector functions. Acts as a receptor on astrocytes for HLA-F. Through interaction with HLA-F, may protect motor neurons from astrocyte-induced toxicity.
