| + | [https://www.uniprot.org/uniprot/ARC1_DROME ARC1_DROME] Master regulator of synaptic plasticity that self-assembles into virion-like capsids that encapsulate RNAs and mediate intercellular RNA transfer from motorneurons to muscles (PubMed:29328915). Arc1 protein is released from motorneurons in extracellular vesicles that mediate the transfer of Arc1 mRNA into muscle cells, where Arc1 mRNA can undergo activity-dependent translation (PubMed:29328915). Intercellular transfer od Arc1 mRNA is required for synaptic plasticity at the neuromuscular junction (PubMed:29328915). May play a role in energy balance: required for regulation of body fat by a specific population of brain neurons, named E347, that are necessary and sufficient for proper body fat storage (PubMed:26209258).<ref>PMID:26209258</ref> <ref>PMID:29328915</ref> | ||

| + | == Publication Abstract from PubMed == | ||
| + | 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. | ||
