Sensing the environment: lessons from fungi

Key Points G-protein-coupled receptors (GPCRs) function as both pheromone and glucose sensors in fungi, whereas transceptors such as Snf3 and Rgt2 are involved in glucose sensing. Fungi have evolved sophisticated amino-acid-sensing systems including Ssy1–Ptr3–Ssy5 (SPS), Gap1 and GPCRs. The transcep...
