TI  - Identification of the HLA-DM/HLA-DR interface.
PG  - 1063-70
AB  - Human leukocyte antigen (HLA)-DM is a critical participant in antigen 
      presentation that catalyzes the dissociation of the Class II-associated Invariant 
      chain-derived Peptide (CLIP) from the major histocompatibility complex (MHC) 
      Class II molecules. There is competition amongst peptides for access to an MHC 
      Class II groove and it has been hypothesised that DM functions as a 'peptide 
      editor' that catalyzes the replacement of one peptide for another within the 
      groove. It is established that the DM catalyst interacts directly with the MHC 
      Class II but the precise location of the interface is unknown. Here, we combine 
      previously described mutational data with molecular docking and energy 
      minimisation simulations to identify a putative interaction site of >4000A2 which 
      agrees with known point mutational data for both the DR and DM molecule. The 
      docked structure is validated by comparison with experimental data and previously 
      determined properties of protein-protein interfaces. A possible dissociation 
      mechanism is suggested by the presence of an acidic cluster near the N terminus 
      of the bound peptide.
