Geranylgeranyl pyrophosphate triammonium is a type of isoprenoid metabolic intermediate, mainly synthesized through the mevalonate pathway. Geranylgeranyl pyrophosphate triammonium is a key precursor in various biological synthesis processes, especially as a necessary substrate for post-translational modification of proteins - geranylgeranyl phosphorylation. Geranylgeranyl pyrophosphate triammonium regulates various cellular processes and disease progression through protein geranylgeranyl phosphorylation, such as activating the YAP signaling pathway, promoting cell proliferation and inhibiting apoptosis, promoting IL-2 production and STAT5 phosphorylation, and influencing metabolic homeostasis and cancer, etc[1][2][3][4][5][6].
