RSK2 is a Ser/Thr kinase acting in the Ras/MAPK pathway. "Rsk2" gene deficiency leads to the Coffin-Lowry Syndrome, notably characterized by cognitive deficits. We found that "mrsk2" knockout mice are unable to associate an aversive stimulus with context in a lithium-induced conditioned place aversion task requiring both high-order cognition and emotional processing. Virally mediated shRNA-RSK2 knockdown in the habenula, whose involvement in cognition is receiving increasing attention, also ablated contextual conditioning. RSK2 signaling in the habenula, therefore, is essential for this task. Our study reveals a novel role for RSK2 in cognitive processes and uncovers the critical implication of an intriguing brain structure in place aversion learning.
