This domain is found in Activity-regulated cytoskeleton-associated protein from humans (Arc), a master regulator of synaptic plasticity that promotes endocytosis of AMPA receptors and a postsynaptic mediator of activity-dependent synapse elimination in the developing cerebellum. This protein is associated with cognitive diseases. This Gag-like protein has the topology of a retroviral Gag protein, with a central capsid domain (this entry) with two globular subdomains, the N-lobe and the C-lobe, consisting of four and five alpha-helices, connected by a short non-helical segment [1-3].
