G proteins are molecules activated by their binding with G protein-coupled receptors (GPCRs).
<h3>What are G proteins?</h3>
G proteins are proteins that act during cellular signaling to transmit information via molecular cascades.
G proteins act by their binding with suitable ligand, where G protein-coupled receptors bind to the G protein and it triggers a molecular cascade.
In conclusion, G proteins are molecules activated by their binding with G protein-coupled receptors (GPCRs).
