The activating NK cell receptor KIR3DS1 has been linked to the outcome of various human diseases, yet a ligand that would account for its biological effects has remained unknown. Altfeld and colleagues establish HLA-F as a ligand of KIR3DS1, which helps to explain the widespread influence of this receptor in disease.
