Abstract excerpt
In the yeast Saccharomyces cerevisiae, the addition of glucose to derepressed cells and intracellular acidification trigger a rapid increase in the cAMP level within 1 min. We have identified a mutation in the genetic background of several related 'wild-type' laboratory yeast strains (e.g. ENY.cat80-7A, CEN.PK2-1C) that largely prevents both cAMP responses, and we have called it lcr1 (for lack of cAMP responses)....
