Drosophila Skywalker regulates the GTPase Rab35, thereby controlling the turnover of synaptic-vesicle proteins. A new crystal structure of the TBC domain of Skywalker reveals an unexpected phosphoinositide-binding pocket, which is critical for synaptic function and is disrupted in DOORS syndrome–causing mutations in the human Skywalker homolog TBC1D24.
