Presynaptic Protein Synthesis in Brain Function and Disease

J Neurosci. 2023 Nov 8;43(45):7483-7488. doi: 10.1523/JNEUROSCI.1454-23.2023.

Abstract

Local protein synthesis in mature brain axons regulates the structure and function of presynaptic boutons by adjusting the presynaptic proteome to local demands. This crucial mechanism underlies experience-dependent modifications of brain circuits, and its dysregulation may contribute to brain disorders, such as autism and intellectual disability. Here, we discuss recent advancements in the axonal transcriptome, axonal RNA localization and translation, and the role of presynaptic local translation in synaptic plasticity and memory.
