THE PROTEIN REMARK 999 CRYSTALLIZED IS THE EXTRACELLULAR LIGAND BINDING REMARK 999 DOMAIN OF GLUR2. TRANSMEMBRANE REGIONS WERE REMARK 999 GENETICALLY REMOVED AND REPLACED WITH A GLY-THR REMARK 999 LINKER (RESIDUES 118 AND 119). THEREFORE, THE REMARK 999 SEQUENCE MATCHES DISCONTINUOUSLY WITH THE REFERENCE REMARK 999 DATABASE (413-527, 653-796). RESIDUES GLY1 AND ALA2 REMARK 999 ARE CLONING ARTIFACTS.
