Yeast Signal Transduction

Emmy walk

Signal transduction is quickly becoming one of biology's most important research areas. This isn't unexpected, given that practically every biological phenomenon includes or is influenced by signalling. A large portion of the signalling molecules in multicellular organisms are used for cell-to-cell communication. Extracellular messengers activate intracellular signal transduction pathways in target cells, altering metabolism, proliferation, and development.
