- 요약Subcellular localization of mRNA is a critical component of spatiotemporal protein expression. Though the earliest observation of mRNA localization was the enrichment of the critical Mbp transcript in oligodendrocyte projections during myelination, mechanistic understanding of this RNA localization phenomenon remains lacking. Here, we profile the entire localized transcriptome of oligodendrocyte projections and begin to dissect the determinants of RNA localization across hundreds of projection-enriched transcripts. Transcripts localized to oligodendrocytes are more stable, translationally active, and have longer 3' UTRs that harbor a variety of cis-acting elements known to regulate mRNA stability and transport. In one illustrative example, we identify a novel cis-acting 3' UTR projection-localizing sequence motif that binds YBX3 and may facilitate RNA localization through compartment-specific RNA degradation. We then turn our sights back on the Mbp 3' UTR to identify a structured cis-acting RNA element that binds hnRNP F and is necessary and partially sufficient for RNA localization to oligodendrocyte projections and translational repression. Our work represents the first transcriptome-wide characterization of mRNA localization to oligodendrocyte projections and substantially improves our understanding of Mbptransport in mammalian myelination.
