Human leukocyte antigen (HLA)-E binds epitopes derived from HLA-A, HLA-B, HLA-C and HLA-G signal peptides (SPs) and serves as a ligand for CD94/NKG2A and CD94/NKG2C receptors. Carrington and colleagues provide comprehensive analysis of classical HLA class I SP variants and show that these can determine CD94/NKG2–HLA-E engagement.
