(Cell 172, 275–288; January 11, 2018) We inadvertently missed citing two relevant papers in the Introduction and Results sections of our paper. Our study is complementary to Ashley et al., 2018Ashley J. Cordy B. Lucia D. Fradkin L.G. Budnik V. Thomson T. Retrovirus-like Gag protein Arc1 binds RNA and traffics across synaptic boutons.Cell. 2018; 172: 262-274Abstract Full Text Full Text PDF PubMed Scopus (221) Google Scholar, published in the same issue of Cell, in showing the homology between Arc and Gag proteins and revealing a new signaling pathway in neurons. We have added a citation to this paper in the Introduction. In addition, Abrusán et al., 2013Abrusán G. Szilágyi A. Zhang Y. Papp B. Turning gold into ‘junk’: transposable elements utilize central proteins of cellular networks.Nucleic Acids Res. 2013; 41: 3190-3200Crossref PubMed Scopus (15) Google Scholar had previously suggested the divergence of fly and tetrapod Arc, and we now mention this paper in the section of the Results with the heading “Fly and Tetrapod Arc Genes Independently Originated from Distinct Lineages of Ty3/gypsy Retrotransposons.” The article has been corrected online to include these references. We apologize for these omissions.
