Complexes of HLA-G protein on the cell surface are important for leukocyte Ig-like receptor-1 function.

Original language description

The nonclassical class I MHC molecule HLA-G is selectively expressed on extravillous cytotrophoblast cells. HLA-G can inhibit the killing mediated by NK cells via interaction with the inhibitory NK cell receptor LIR-1. Comparison of the sequence of the HLA-G molecule to other class I MHC proteins revealed two unique cysteine residues 42 and 147. Mutating these cysteine residues resulted in a dramatic decrease in LIR-1 Ig binding. The mutated HLA-G transfectants were less effective in the inhibition of NK killing. The involvement of the cysteine residues in the formation of HLA-G protein oligomers was demonstrated. The cysteine residue 42 is critical for the expression of such complexes. These oligomers, unique among the class I MHC proteins, probably bind to LIR-1 with increased avidity, resulting in an enhanced inhibitory function of LIR-1 and an impaired killing function of NK cells.
