Roles for sphingolipid biosynthesis in mediation of specific programs of the heat stress response determined through gene expression profiling.

Abstract excerpt

Previous studies have demonstrated roles for de novo production of sphingolipids in Saccharomyces cerevisiae in the regulation of the transient cell cycle arrest and nutrient permease degradation associated with the heat stress response, suggesting multiple functions for yeast sphingolipids in this response. We, therefore, sought to determine the generalized involvement of sphingolipids in the heat stress...
