Guanosine diphosphate ( GDP ) is the diphosphate of the nucleoside guanosine . It plays an important role as a cellular energy carrier and breakdown product of guanosine triphosphate . Guanosine diphosphate is also involved as a cofactor of G proteins in the transmission of external stimuli into the cell interior ( signal transduction ).

GDP is produced in the cell by dephosphorylation of guanosine triphosphate (GTP) by GTPases .
