All signaling pathways must be turned off as well as
turned on. Consider the pathways started by GPCR, and the JAK/STAT
pathway.
1) Draw each pathway, from ligand binding to some sort
of cellular effect.
2) In your drawing, indicate how each step of the
pathway is inactivated, including the type of enzyme that
inactivates it if relevant (e.g. phosphatase, GAP,
etc)
