Abstract and Keywords

This chapter reviews current developments in the area of translational control in neurons. It focuses on the activity-dependent translational modulation by neuronal regulatory RNAs, including underlying interactions with eukaryotic initiation factors (eIFs), and on the role of such modulation in locally controlled protein synthesis in synapto-dendritic domains. It highlights the role of dendritic RNA targeting as a key prerequisite of local translation at the synapse and discusses the significance of these mechanisms in the expression of higher brain functions, including learning, memory, and cognition. The chapter concludes with discussion of anticipated future work to continue to elucidate these mechanisms and provide advances in the area of translational regulation in neurons and our understanding of how translational dysregulation contributes to neurological and cognitive disorders.

Keywords: local protein synthesis, regulatory RNAs, synapses, translational control, translation initiation factors, RNA transport
