In Cell Chemical Biology, Naineni et al. (2021) report the structure of a synthetic analog of the translation inhibitor pateamine A bound to initiation factor eIF4A and RNA. The drug stacks with RNA bases in the same pocket where unrelated rocaglate compounds bind, highlighting a druggable site for DEAD-box proteins.Astrocyte-secreted Hevin induces synapse formation by bridging the trans-synaptic organizers, neuroligins and neurexins. In this issue of Structure, Fan et al. (2021) elucidate the structural basis of Hevin's intera
