The Arc protein modulates the trafficking of AMPA-type glutamate receptors. This domain's tertiary structure is similar to the capsid domain of HIV gag protein. The domain is thought to have evolved from the capsid domain of Ty3/Gypsy retrotransposon [1-4].

This protein is associated with cognitive diseases. This protein has a bi-lobar architecture that is similar to the capsid domain of HIV gag protein consisting of a N-lobe, represented in this entry, and a C-lobe (Pfam:PF18162), which have four and five alpha-helices, connected by a short non-helical segment [1-3]. This protein was originated from the Ty3/Gypsy retrotransposon family and domesticated in higher vertebrates for synaptic functions [1].
