This course is focused on the molecular aspects of signal transduction, covering how cells receive and then transmit signals via intracellular proteins such as kinases and phosphatase and how this ultimately regulates cell function. Specific topics covered include regulation and signalling by extracellular ligands including morphogens, growth factors and/or insulin, how signalling pathway crosstalk modulates cell function and low and high throughput methodological approaches used to elucidate signalling mechanisms.
