The Rai1-Tag knock-in allele expresses a FLAG/myc-tagged RAI1 (Rai1-Tag) before Cre recombinase exposure. Cre-mediated deletion of the floxed FLAG-myc-STOP sequence results in expression of RAI1/EGFP fusion protein (Rai1EGFP).
To better understand how the brain processes information and generates behavior, researchers in Dr. Liqun Luo's lab have generated the FosTRAP and ArcTRAP mouse strains.
