Abstract
To investigate the mechanisms used in eukaryotes to maintain translational accuracy, we and others have isolated and characterized mutations that affect the fidelity of protein synthesis in yeast. These mutations include nonsense suppressors that cause misreading of specific stop codons; omnipotent suppressors, which cause general translational inaccuracy and suppression of UAG, UAA, and UGA codons; and allosuppressors and antisuppressors, which respectively enhance or lower the efficiency of certain suppressors. Using this layered approach we should identify translational components that are likely to interact. Recently the genetic work has been extended by cloning and characterizing the mutant genes. We have also identified components of the translational apparatus important for fidelity by selecting for wild-type genes that alter accuracy when present at higher copy number. Below we summarize our work in this area.
