ProteomicsLC-MSMS of DCC and Neuropilin-1 immunoprecipitated samples from Xenopus Laevis brains
During neuronal wiring, extrinsic cues trigger the local translation of specific mRNAs in axons via cell surface receptors. The coupling of ribosomes to receptors has been proposed as a mechanism linking signals to local translation but it is not known how broadly this mechanism operates, nor whethe...

ProteomicsRegulated local synthesis of ribosomal proteins maintains ribosome function in axons
Ribosome assembly occurs mainly in the nucleolus yet recent studies have revealed robust enrichment and translation of mRNAs encoding many ribosomal proteins (RPs) in axons, far away from neuronal cell bodies. Here, we report a physical and functional interaction between locally synthesized RPs and ...

ProteomicsSILAC-labeled proteins in ribosome samples
we developed a novel method combining axon-pSILAC17 with axonal ribosome purification. In this method, we first labeled newly synthesized proteins with heavy amino acids (AAs) in somaless axons cultured in a Boyden chamber. Approximately 2000 eyes were cultured for each experiment to obtain sufficie...

TranscriptomicsSubcellular expression profiling of the growth cones of retinal ganglion cells (RGC)
Cue-directed axon guidance depends partly on local translation in growth cones. Many mRNA transcripts are known to reside in developing axons yet little is known about their subcellular distribution or, specifically, which transcripts are in growth cones. Laser capture microdissection (LCM) was used...

TranscriptomicsmiR-124 acts through coREST to control the onset of Sema3A sensitivity in navigating retinal growth cones
During axon pathfinding, growth cones commonly exhibit changes in sensitivity to guidance cues that follow a strict timetable, even in the absence of pathway feedback, implicating cell-intrinsic regulation. Cellular timer mechanisms, however, are poorly understood. Here we have investigated microRNA...
