2
Q
what are the the two main types of GTP-binding proteins?
A
- trimeric G proteins
- monomeric GTPases
3
Q
what happens at G-protein coupled receptors?
A
- ligands bind to GPCRs and activate associated G protein
2. activated G protein inhibits/activates a downstream enzyme to generate intracellular second message
