Title : Crystal structure of mouse H2-M
Abstract :
- H2-M ( HLA-DM in humans) resides in an acidic endosomal compartment, where it facilitates the loading of antigenic peptides into the peptide-binding groove of class II MHC
- The crystal structure of a soluble form of H2-M has been solved to 3.1 A resolution, revealing a heterodimer with structural similarities to the MHC family of proteins
- In contrast to its antigen-presenting cousins, the membrane distal alpha helices of H2-M pack closely together, occluding most of the binding groove except for a single large pocket near the center
- The structure of H2-M has several unique features that may play a role in its function as a molecular chaperone and peptide exchange factor
