Crystal Structure of the free human NKG2D immunoreceptor
Overview
Engagement of diverse protein ligands (MIC-A/B, ULBP, Rae-1, or H60) by, NKG2D immunoreceptors mediates elimination of tumorigenic or virally, infected cells by natural killer and T cells. Three previous NKG2D-ligand, complex structures show the homodimeric receptor interacting with the, monomeric ligands in similar 2:1 complexes, with an equivalent surface on, each NKG2D monomer binding intimately to a total of six distinct ligand, surfaces. Here, the crystal structure of free human NKG2D and in silico, and in vitro alanine-scanning mutagenesis analyses of the complex, interfaces indicate that NKG2D recognition degeneracy is not explained by, a classical induced-fit mechanism. Rather, the divergent ligands appear to, utilize different strategies to interact with structurally conserved, elements of the consensus NKG2D binding site.
