Crystal Structure of the Glur2 Amino-Terminal Domain Provides Insights Into the Architecture and Assembly of Ionotropic Glutamate Receptors.
J.Mol.Biol., 392:1125-, 2009

PubMed Abstract: Ionotropic glutamate receptors are functionally diverse but have a common architecture, including the 400-residue amino-terminal domain (ATD). We report a 1.8-A resolution crystal structure of human GluR2-ATD. This dimeric structure provides a mechanism for how the ATDs can drive receptor assembly and subtype-restricted composition. Lattice contacts in a 4.1-A resolution crystal form reveal a tetrameric (dimer-dimer) arrangement consistent with previous cellular and cryo-electron microscopic data for full-length AMPA receptors.
