| Remark 400 | COMPOUND NATIVE GLUR2 IS A MEMBRANE PROTEIN. S1S2J COMPRISES THE LIGAND BINDING CORE OF THE PROTEIN. ...COMPOUND NATIVE GLUR2 IS A MEMBRANE PROTEIN. S1S2J COMPRISES THE LIGAND BINDING CORE OF THE PROTEIN. TRANSMEMBRANE PARTS OF THE PROTEIN HAVE BEEN REPLACED BY A GLY-THR LINKER (RESIDUES 115-116). THEREFORE, THE SEQUENCE MATCHES DISCONTINUOUSLY WITH THE REFERENCE DATABASE. | ||||||
| Remark 999 | SEQUENCE Residues 528-652 in dbref have been replaced by a Gly-Thr (115-116) linker |
