FunctionRAE1B_MOUSE Acts as a ligand for NKG2D.[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedInduced by retinoic acid and implicated in playing a role in development, rodent RAE-1 proteins are ligands for the activating immunoreceptor NKG2D, widely expressed on natural killer cells, T cells, and macrophages. RAE-1 proteins (alpha, beta, gamma, and delta) are distant major histocompatibility complex (MHC) class I homologs, comprising isolated alpha1alpha2 platform domains. The crystal structure of RAE-1beta was distorted from other MHC homologs and displayed noncanonical disulfide bonds. The loss of any remnant of a peptide binding groove was facilitated by the close approach of the groove-defining helices through a hydrophobic, leucine-rich interface. The RAE-1beta-murine NKG2D complex structure resembled the human NKG2D-MICA receptor-ligand complex and further demonstrated the promiscuity of the NKG2D ligand binding site.
