ジャーナル: Nat Neurosci / 年: 2020 タイトル: Structures of virus-like capsids formed by the Drosophila neuronal Arc proteins. 著者: Simon Erlendsson / Dustin R Morado / Harrison B Cullen / Cedric Feschotte / Jason D Shepherd / John A G Briggs / 要旨: Arc, a neuronal gene that is critical for synaptic plasticity, originated through the domestication of retrotransposon Gag genes and mediates intercellular messenger RNA transfer. We report high- ...Arc, a neuronal gene that is critical for synaptic plasticity, originated through the domestication of retrotransposon Gag genes and mediates intercellular messenger RNA transfer. We report high-resolution structures of retrovirus-like capsids formed by Drosophila dArc1 and dArc2 that have surface spikes and putative internal RNA-binding domains. These data demonstrate that virus-like capsid-forming properties of Arc are evolutionarily conserved and provide a structural basis for understanding their function in intercellular communication.
