Nakamuta et al.&amp;nbsp;reveal that the Rac\/Cdc42 guanine nucleotide exchange factor DOCK7 coordinates this migratory cycle by regulating both Rac-dependent leading process extension and p116Rip-dependent actin assembly at the cell rear. This biosights episode presents the paper by Nakamuta et al. from the December 4th, 2017, issue of&amp;nbsp;The Journal of Cell Biology&amp;nbsp;and includes an interview with the paper's senior author, Linda Van Aelst (Cold Spring Harbor Laboratory, NY). Produced by Caitlin Sedwick and Ben Short. See the associated paper in&amp;nbsp;JCB&amp;nbsp;for details on the funding provided to support this original research.
