The sphingoid long chain base phytosphingosine activates AGC-type protein kinases in Saccharomyces cerevisiae including Ypk1, Ypk2, and Sch9.

Abstract excerpt

The Pkh1 protein kinase of Saccharomyces cerevisiae, a homolog of the mammalian 3-phosphoinositide-dependent kinase (PDK1), regulates downstream AGC-type protein kinases including Ypk1/2 and Pkc1, which control cell wall integrity, growth, and other processes. Phytosphingosine (PHS), a sphingoid long chain base, is hypothesized to be a lipid activator of Pkh1 and thereby controls the activity of Ypk1/2. Here we...
