SCA31 Flies Perform in a Balancing Act between RAN Translation and RNA-Binding Proteins

In this issue of Neuron, Ishiguro et al. (2017) explore the toxicity of RAN translation in spinocerebellar ataxia 31. Using a Drosophila model, the authors demonstrate that TDP-43 and other RNA-binding proteins act as chaperones to regulate the formation of toxic RNA aggregates.
