Gdp phosphorylation
WebMar 5, 2024 · The encoded protein inhibits the disassociation of Rho family members from GDP (guanine diphosphate), thereby maintaining these factors in an inactive state. … WebThe G s alpha subunit of the stimulated G protein complex exchanges GDP for GTP and is released from the complex. In a cAMP-dependent pathway, the activated G s alpha subunit binds to and activates an enzyme called adenylyl cyclase, which, in turn, catalyzes the conversion of ATP into cyclic adenosine monophosphate (cAMP).
