The authors show that phosphorylation of the translation factor eIF2α is necessary and sufficient for mGluR-LTD. They identify mRNAs that are translated during mGluR-LTD and regulated by p-eIF2α, including Ophn1 as a key target. Deficient p-eIF2α-mediated translation impairs object-place learning, which requires mGluR-LTD. eIF2α phosphorylation may determine whether synapses undergo LTD or LTP.
