Remark 999 | Sequence The native GLUR-2 is a membrane protein. The protein crystallized by the author is the ...Sequence The native GLUR-2 is a membrane protein. The protein crystallized by the author is the extracellular ligand binding domain of GLUR-2. Transmembrane regions were genetically removed and replaced with a Gly-Thr linker. The sequence, as a result, matches discontinuously with the reference database. |
