Guanosine TriPhosphate


View on Cell Map View on Scale Diagram

Pathway Narrative:

GTP is swapped for GDP upon activation of the G protein, resulting in dissociation of the G Alpha subunit.

Small Molecule
Acts as a battery for G-Protein signal transmission
Interacts with:
G Protein, G alpha Subunit
Interesting Facts:

GTP and ATP have the same amount of energy but ATP is much more prevalent in the cell. Just like ATP, one component of GTP and GDP, guanine, is one of the four base pairs that compose DNA and RNA.
