Schematic diagram of the proximal promoter regulatory regions of glutamate receptors. The proximal promoter regions of the GluN1, GluN2A, GluN2B, and GluN2C NMDA receptors, the GluA1 and GluA2 AMPA receptors, and the GluK5 kainate receptor are shown. Promoters are shown as thin lines and introns as thin lines with hashmarks. The 5′-untranslated exon sequences are represented by open bars; blackened bars designate the protein coding domains. Glutamate receptor regulatory elements are identified; those requiring further confirmation are in parentheses. The promoter regions are not drawn to scale.
