| Remark 999 | Sequence Native GluR2 is a membrane protein. The protein crystallized is the extracellular ligand ...Sequence Native GluR2 is a membrane protein. The protein crystallized is the extracellular ligand binding domain of GluR2. Transmembrane regions were genetically removed and replaced with a GLY-THR linker (residues 118 and 119). Therefore, the sequence matches discontinuously with the reference database (413-527, 653-796). Residues GLY1 and ALA2 are cloning artifacts. |
