Signal Transduction Mechanisms 4/12/16 Yeast Can be diploid or haploid If a cell can recognize the presence of another cell nearby it develops a schmoo which allows the cells to mate Cell communication is more complicated in multicellular organisms Multiple potentials before differentiation Communication is crucial Signal transduction moves information from the cell surface to the nucleus & other cellular targets Converts an outside message into a change in cell behavior Signal transduction Extracellular signal is converted to intracellular signals that direct cell behavior Cell communications depends on: Extracellular signal molecules Receptor proteins Intracellular signaling proteins Target proteins What type of molecules can be used as extracellular signals? Proteins
