Abstract excerpt
In Saccharomyces cerevisiae, disruption of both protein phosphatase genes, PTP2 and MSG5, causes calcium sensitivity while additional disruption of protein kinase genes BCK1, MKK1, SLT2, MCK1, YAK1 and SSK2 confers calcium tolerance. Although the roles of BCK1, MKK1 and SLT2 have been characterized recently, the mechanism of suppression of the calcium sensitivity by SSK2 disruption is poorly understood. In this...
