In this issue of Neuron, Amin et al. (2021) generate genetic tools to titrate down levels of miR-218, a motor neuron-enriched microRNA, in vivo. Varying miR-218 dose alters target selection, results in distinct dose-response curves reflecting 3' UTR features, and reveals a miR-218 threshold below which motor neuron deficits emerge.
