Structure of an Arc-ane virus-like capsid

Recent findings unveil a viral-like mechanism for the transmission of synaptic plasticity signals involving the activity-regulated cytoskeleton-associated protein (Arc). Arc forms capsid-like particles that package RNA and are transported across synapses. Here Erlendsson et al. present a high-resolution structural representation of Arc capsids, enabling deeper analysis of their function.
