Two different protein kinase activities phosphorylate RAS2 protein in Saccharomyces cerevisiae

In this report, we show that Raen protein in the yeast Saccharomycescerevisiae is phosphorylated invivo by protein kinase(s) and the phosphorylation is stable. Raen protein is phosphorylated by cAMP dependent protein kinase and by an additional protein kinase activity which is independent of cAMP levels
