- Pathway Narrative:
GDP is bound by inactive G proteins at the G Alpha site.
- Small Molecule
- Acts as a byproduct of signal transmission
- Interacts with:
- G Protein, G alpha Subunit
- Interesting Facts:
GDP is the product of GTP dephosphorylation by GTPases, e.g., the G-proteins that are involved in signal transduction. GDP is converted into GTP with the help of pyruvate kinase and phosphoenolpyruvate.
