EIF2A and infection: To further explore the effect of eIF2α phosphorylation on the repression of host translation and selective protein synthesis of MG1 proteins, we performed [35S]-methionine labeling in phosphor-null eIF2α (S51A) immortalized MEFs and the genetically-paired wild type MEFs following a time-course of infection with MG1 virus at MOI of 0.1 (Figure 3).
