In this study, Sivadasan et al. show that the interactome of the C9ORF72 protein contains cofilin and other actin-binding proteins. They also demonstrate that actin dynamics are reduced in patient-derived motor neurons and tissues with ALS-related intronic expansion of the C9ORF72 gene, leading to altered axon growth and growth cone dynamics.
