A Bioluminescence Reporter Assay for Retinoic Acid Control of Translation of the GluR1 Subunit of the AMPA Glutamate Receptor

AbstractThe present protocol describes a bioluminescence reporter assay developed to quantify the ability of synthetic agonists of retinoic acid receptors (RARs) to activate glutamate receptor subunit 1 (GluR1) translation. The reporter assay uses firefly luciferase under the control of the GluR1 5′ untranslated region (5′ UTR) which is bound by RARs to regulate its translation. This method is used to demonstrate the role of RARα in retinoic acid regulation of GluR1 translation. This method may also be used to screen drugs that influence RAR induction of GluR1 translation as an important mechanism controlling learning and memory in the brain.Key words GluA1 Gria1 GluR1 RetinoidNon-genomicCytoplasmSynaptic scaling
