We propose that GCD7 and GCD2 play important roles in the regulatory interaction between eIF - 2 and eIF - 2B and that the suppressor mutations we isolated in these genes decrease the susceptibility of eIF - 2B to the inhibitory effects of phosphorylated eIF - 2 without impairing the essential catalytic function of eIF - 2B in translation initiation .
