"Study shows that the prion-like domain (PLD) of Drosophila Imp is essential for the developmentally-controlled localization of Imp ribonucleoprotein (RNP) granules to axons and regulates in vivo axonal remodeling. Imp PLD restricts granule assembly revealing a novel function for PLDs in RNP granule homeostasis. Study uncovers a physiological function for PLDs in the spatio-temporal control of neuronal RNP assemblies."xsd:string
