THE CRYSTAL STRUCTURE OF H-2DB COMPLEXED WITH A PARTIAL PEPTIDE EPITOPE SUGGESTS AN MHC CLASS I ASSEMBLY-INTERMEDIATE

Overview

In the absence of bound peptide ligands, major histocompatibility complex, (MHC) class I molecules are unstable. In an attempt to determine the, minimum requirement for peptide-dependent MHC class I stabilization, we, have used short synthetic peptides derived from the Sendai virus, nucleoprotein epitope (residues 324-332, 1FAPGNYPAL9) to promote its, folding in vitro of H-2D(b). We found that H-2D(b) can be stabilized by, the pentapeptide 5NYPAL9, which is equivalent to the C-terminal portion of, the optimal nonapeptide and includes both the P5 and P9 anchor residues., We have crystallized the complex of the H-2D(b) molecule with the pentamer, and determined the structure to show how a quasi-stable MHC class I, molecule can be formed by occupancy of a single binding pocket in the, ...
