GluR4 C terminal. A, Schematic diagram of the C-terminal region of GluR4, including the fourth transmembrane domain (TMD IV). Theexpanded region shows the amino acid sequence of the C terminal, and the residues subjected to site-directed mutagenesis are indicated by their residue numbers. Thearrows indicate the ending of the truncated C-terminal bacterial fusion proteins. B, Schematic diagram of the fusion proteins containing segments of GluR4 C terminal.
