Synaptogenesis Stimulates a Proteasome-Mediated Ribosome Reduction in Axons

WebbRibosomes are degraded by ubiquitin proteasome system upon axonal maturation Summary Ribosomes and a subset of cellular mRNAs are trafficked into axons of developing neurons. The axonal localization of translational machinery allows new proteins to be rapidly and locally synthesized during axonal growth and pathfinding. 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. cminusfan4 merch
