Human histocompatibility leukocyte antigen (HLA)-DM edits peptides presented by HLA-DR according to their ligand binding motifs

Human histocompatibility leukocyte antigen (HLA)-DM is a facilitator of antigen presentation via major histocompatibility complex (MHC) class II molecules. In the absence of HLA-DM, MHC class II molecules do not present natural peptides, but tend to remain associated with class II- associated invariant chain peptides (CLIP). Recently, DM was shown to catalyze the release of CLIP from HLA-DR. We have investigated which peptides bound to HLA-DR are vulnerable to release upon encountering DM. By directed substitution of allele-specific anchor residues between CLIP and DR3-cognate peptides and the application of recombinant DM we show that DM catalyzes the release of those peptides bound to HLA-DR3 that do not have appropriate anchor residues and, hence, no optimal ligand binding motif. Thus, HLA-DM acts as a peptide editor, facilitating selection of peptides that stably bind to class II molecules for eventual presentation to the immune system from the pool of available peptides.
