Peptide-induced conformational change of the class I heavy chain.
There is evidence that peptide ligands take part in the assembly of class I molecules. In particular, addition of peptides to extracts of the mutant cells RMA-S and .174/T2, in which stable assembly of class I does not occur, results in a conformational change in the class I heavy chain and stable association of the heavy chain with beta 2-microglobulin (beta 2m). Thus specific peptides may stabilize or induce a conformational change in the class I heavy chain that results in a rise in the bi...Expand abstract
