CRYSTAL STRUCTURE OF MOUSE H2-DM

Overview

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.

About this Structure

1K8I is a Protein complex structure of sequences from Mus musculus with as ligand. Full crystallographic information is available from OCA.
