MHC class I molecules are expressed by all nucleated cells of the body. They bind small fragments of protein from inside a cell and present these at the cell surface. CD8-positive T cells and NK cells can detect infected or damaged cells by scanning MHC class I molecules. Latest Research ...
Class I MHC molecules present peptide antigens derived from intracellular proteins to T cell receptors on cytotoxic T lymphocytes. The dual recognition properties of T cell receptors; that is, recognition of both the antigen and the MHC protein, were not understood until 3-dimensional structures of...
The MHC class I molecule is a three-domain protein that forms a peptide-binding groove such that antiparallel β sheets form the floor of the groove and α helices form the sides of the groove. From: The Enzymes, 2017 About this pageAdd to MendeleySet alert ...

2009. Insights into MHC class I peptide loading from the structure of the tapasin- ERp57 thiol oxidoreductase heterodimer. Immunity 30: 21-32.Dong, G., Wearsch, P.A., Peaper, D.R., Cresswell, P. & Reinisch, K.M. Insights into MHC class I peptide loading from the structure of the...
the MHC class I peptide-binding groove and to stabilize the MHC fold in partially empty crystal structures16, we switched to crystals of dsA2/GM that formed in the presence of 1,2-ethanediol (EDO) at 10 mm free dipeptide and determined a crystal structure of dsA2 at 1.6 Å (Fig...
The present invention is directed to a novel targeted vaccine delivery system, comprising one or more peptide-MHC Class I complexes linked through the β 2 -microglobulin molecule to an antibody which is specific for a cell surface marker. The complexes of the invention contain a β 2 -microglo...

The crystal structure of this ligand-receptor complex that we report here reveals an NKG2D homodimer bound to a MICA monomer in an interaction that is analogous to that seen in T cell receptor-MHC class I protein complexes. Similar surfaces on each NKG2D monomer interact with different surfaces ...
Both classical and non-classical class I molecules have a conserved and distinctive protein domain structure. MHC class I genes typically have 5–9 exons encoding proteins with well-defined domain organization (Fig. 1a and 1b). The first exon encodes a signal peptide. Exons 2 and 3 encode th...
