Juxtaposition of domains homologous to protein kinases and histidyl-tRNA synthetases in GCN2 protein suggests a mechanism for coupling GCN4 expression to amino acid availability.
The GCN2 protein of Saccharomyces cerevisiae stimulates the expression of amino acid biosynthetic genes under conditions of amino acid starvation by derepressing GCN4, a transcriptional activator of these genes. GCN2 contains sequences homologous to the catalytic domain of protein kinases. We show h...
