General principles of cellular communication

Learning outcomes

After studying this course, you should be able to:

  • describe in general terms how extrinsic signals activate cell signalling pathways to elicit cellular responses
  • describe how cell signalling processes facilitate quorum sensing in bacteria
  • outline the diverse roles played by proteins in cellular communication and how various proteins can function together in a signalling pathway
  • relate the activities and properties (including domain structure) of proteins to their roles in signalling.
