Probing Pathways Periodically

Abstract: Signal transduction pathways are used by cells to process and transmit information about their external surroundings. These systems are dynamic, interconnected molecular networks. Therefore, full characterization of their behavior requires a systems-level analysis. Investigations with temporally oscillating input signals probed the dynamic properties of the high-osmolarity glycerol (HOG) pathway of the budding yeast Saccharomyces cerevisiae. These studies shed light on how the network functions as a whole to respond to changing environmental conditions.
