Remark 999 | Native GluR2 is a membrane protein. The protein crystallized is the extracellular ligand-binding ...Native GluR2 is a membrane protein. The protein crystallized is the extracellular ligand-binding core of GluR2. Transmembrane regions were genetically removed and replaced with a Gly-Thr linker (residues 118-119). Therefore, the sequence matches discontinuously with the reference database (413-527, 653-796). The two first residues (Gly, Ala) are cloning artifacts and were not located in the electron density map. |
