Abstract excerpt
The GCN4 protein of S. cerevisiae is a transcriptional activator of amino acid biosynthetic genes which are subject to general amino acid control. GCN3, a positive regulator required for increased GCN4 expression in amino acid-starved cells, is thought to function by antagonism of one or more negative regulators encoded by GCD genes. We isolated gcn3c alleles that lead to constitutively derepressed expression of...
