Emerging Roles for 3' UTRs in Neurons.

ABSTRACT: The 3' untranslated regions (3' UTRs) of mRNAs serve as hubs for post-transcriptional control as the targets of microRNAs (miRNAs) and RNA-binding proteins (RBPs). Sequences in 3' UTRs confer alterations in mRNA stability, direct mRNA localization to subcellular regions, and impart translational control. Thousands of mRNAs are localized to subcellular compartments in neurons-including axons, dendrites, and synapses-where they are thought to undergo local translation. Despite an established role for 3' UTR sequences in imparting mRNA localization in neurons, the specific RNA sequences and structural features at play remain poorly understood. The nervous system selectively expresses longer 3' UTR isoforms via alternative polyadenylation (APA). The regulation of APA in neurons and the neurona
