摘要	Subcellular targeting and local translation of mRNAs are critical for axon development. However, the precise local control of mRNA translation requires investigation. We report that the Fmr1-encoded protein, FMRP-mediated axonal delivery of miR-181d negatively regulates axon elongation by locally targeting the transcripts of MAP1B (Map1b) and calmodulin (Calm1) in primary sensory neurons. miR-181d affected the local synthesis of MAP1B and calmodulin in axons. FMRP was associated with miR-181d, Map1b, and Calm1. Both FMRP deficiency in Fmr1(I304N) mice and Fmr1 knockdown impeded the axonal delivery of miR-181d, Map1b, and Calm1 and reduced the protein levels of MAP1B and calmodulin in axons. Furthermore, nerve growth factor (NGF) induced Map1b and Calm1 release from FMRP and miR-181d-repressing granules, thereby promoting axon elongation. Both miR-181d overexpression and FMRP knockdown impaired NGF-induced axon elongation. Our study reveals a mechanism for the local regulation of translation by miR-181d and FMRP during axon development.
