Webb31 jan. 2024 · Polysome profiling of microdissected regions was used to determine the association of axonal and/or dendritic and somatic transcripts, respectively, with monosomes or polysomes. Ribosome footprinting was then used to assess the translational activity of monosomes (single ribosomes) and polysomes. WebbRibosome 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 ri- bosomesintheaxon.
Webb19 dec. 2024 · Ribosomes are known to be assembled in the nucleolus, yet recent studies have revealed robust enrichment and translation of mRNAs encoding ribosomal proteins (RPs) in axons, far away from neuronal cell bodies. Using subcellular proteomics and live-imaging, we show that locally synthesized RPs incorporate into axonal ribosomes in a … WebbThe synthesis of these substances can occur in the terminal itself, but the synthesizing enzymes are formed by ribosomes in the soma and must be transported down the axon to the terminal. This process is known as axoplasmic flow; it occurs in both directions along the axon and may be facilitated by microtubules.
