(Submitter supplied) 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 ribosomes in the axon. We show that axonal RP translation is regulated through a novel sequence motif, CUIC, that forms an RNA-loop structure in the region immediately upstream of the initiation codon. more...

(Submitter supplied) Local mRNA translation mediates the adaptive responses of axons to extrinsic signals but direct evidence that it occurs in mammalian CNS axons in vivo is scant. We developed an axon-TRAP-RiboTag approach in mouse that allows deep-sequencing analysis of ribosome-bound mRNAs in the retinal ganglion cell axons of the developing and adult retinotectal projection in vivo. The embryonic-to-postnatal axonal translatome comprises an evolving subset of enriched genes with axon-specific roles suggesting distinct steps in axon wiring, such as elongation, pruning and synaptogenesis. more...

(Submitter supplied) Local mRNA translation in axons is critical for the spatial and temporal regulation of the axonal proteome. A wide variety of mRNAs are localized and translated in axons, however how protein synthesis is regulated at specific subcellular sites in axons remains unclear. Here, we establish that the axonal endoplasmic reticulum (ER) supports axonal translation in developing neurons. Axonal ER tubule disruption impairs local translation and ribosome distribution. more...

(Submitter supplied) Precise spatiotemporal control of mRNA translation machinery is essential to proper development of highly complex systems like the neocortex. Here, we show that an RNA-binding protein, Hu antigen R (HuR), regulates both neocorticogenesis and specificity of neocortical translation machinery in a developmental stage-dependent manner in mice. Neocortical absence of HuR alters the phosphorylation states of the initiation and elongation factors of the core translation machinery. more...

(Submitter supplied) Emerging studies have linked the ribosome to more selective control of gene regulation. However, an outstanding question is whether ribosome heterogeneity at the level of core ribosomal proteins (RPs) enables ribosomes to preferentially translate specific mRNAs genome-wide. Here, we measured the absolute abundance of RPs in translating ribosomes and profiled transcripts that are enriched or depleted from select subsets of ribosomes within embryonic stem cells. more...

(Submitter supplied) 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 whether it can selectively regulate mRNA translation. We report that receptor-ribosome coupling is employed by multiple guidance cue receptors and this interaction is mRNA-dependent. more...

(Submitter supplied) We used ribosome profiling to characterize the biological role of ribosome recycling factor (RRF) in Escherichia coli. As expected, RRF depletion leads to enrichment of post-termination 70S complexes in 3′-UTRs. We also observe that elongating ribosomes are unable to complete translation because they are blocked by non-recycled ribosomes at stop codons. Previous studies have suggested a role for recycling in translational coupling within operons; if a ribosome remains bound to an mRNA after termination, it may re-initiate downstream. more...

(Submitter supplied) This study uncovers a population of eRpL22 paralogue-specific specialized ribosomes in the fly testis. Wildtype testes were used to isolate eRpL22 paralogue-specific ribosomes complexed with RNA molecules. RNA-sequencing determined the distribution of RNAs (mRNA and ncRNA) on each type of eRpL22 paralogue-specific ribosome, revealing unique translatomes for both eRpL22- and eRpL22-like- ribosomes, as well as an overlapping translatome.

Here, we present “nanoRibo-seq” an optimized approach using 102- to 103-fold less input material than bulk approaches. nanoRibo-seq exhibits rigorous quality control features consistent with quantification of ribosome protected fragments with as few as 1,000 cells. more...

(Submitter supplied) Ribosomal protein genes (RPGs) coding sequences are highly conserved along evolution; however, promoter features and the machinery involved in their transcriptional regulation are not. In eukaryotes, the main genomic elements and players involved in RPG transcriptional regulation have been mostly characterized in Saccharomyces cerevisiae. However, given the lack of evolutionary conservation of the yeast factors, studies in higher eukaryotes have focused on searching for differential enrichment of transcription factor-binding motifs within the RPG promoters. more...

(Submitter supplied) Local protein synthesis has not been believed to occur in adult forebrain axons. We have used translating ribosome affinity purification (TRAP) to capture mRNA from the distal amygdaloid projections of auditory cortical axons.
