== Publication Abstract from PubMed ==
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 peptide-binding groove.
