LEARN MORE
Pathway Narrative:

G proteins are bound by activated GLP-1R to become active, resulting in dissociation into two smaller subunits.

Type:
Protein
Function/Job:
Acts as a signal carrier along the membrane
Interacts with:
GLP1R, GTP, GDP
Interesting Facts:

The G-protein is composed of three smaller subunits- alpha, beta and gamma. They bind to activated G protein-coupled receptors in order to propagate an external signal along the membrane.
