Nutrient sensing and cAMP signaling in yeast: G-protein coupled receptor versus transceptor activation of PKA

Griet Van Zeebroeck1,2,†, Liesbeth Demuyser1,2,†, Zhiqiang Zhang1,2, Ines Cottignie1,2 and Johan M. Thevelein1,2

The herein presented work supports a model, in which nutrient transceptors are evolutionary ancestors of GPCRs, employing a more primitive direct signaling mechanism compared to the indirect cAMP second-messenger signaling mechanism used by GPCRs for activation of PKA.
