Guanosine TriPhosphate
GTP
LEARN MORE
- Pathway Narrative:
GTP is swapped for GDP upon activation of the G protein, resulting in dissociation of the G Alpha subunit.
- Type:
- Small Molecule
- Function/Job:
- 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.
