Extracellular cues are recognized by G-protein-coupled receptors which transmit the signal via trimeric G proteins to their cellular effectors. Dr. Eduard Stefan from the Institute of Biochemistry showed in cooperation with international research teams a novel and conserved mechanism how cells adapt to environmental changes.
