The Individual

In neurons, mRNAs are transported to distal sites to allow for localized protein synthesis. There are many diverse mechanisms underlying this transport. For example, an individual mRNA can be transported in an RNA transport particle that is tailored to the individual mRNA and its associated binding proteins. In contrast, some mRNAs are transported in liquid-liquid phase separated structures called neuronal RNA granules that are made up of multiple stalled polysomes, allowing for rapid initiation-independent production of proteins required for synaptic plasticity. Moreover, neurons have additional types of liquid-liquid phase–separated structures containing mRNA, such as stress granules and P bodies. This chapter discusses the relationships between all of these structures, what proteins distinguish them, and the possible roles they play in the complex control of mRNA translation at distal sites that allow neurons to use protein synthesis to refine their local proteome in many different ways.
