Function

FPPS_HUMAN Key enzyme in isoprenoid biosynthesis which catalyzes the formation of farnesyl diphosphate (FPP), a precursor for several classes of essential metabolites including sterols, dolichols, carotenoids, and ubiquinones. FPP also serves as substrate for protein farnesylation and geranylgeranylation. Catalyzes the sequential condensation of isopentenyl pyrophosphate with the allylic pyrophosphates, dimethylallyl pyrophosphate, and then with the resultant geranylpyrophosphate to the ultimate product farnesyl pyrophosphate.

Publication Abstract from PubMed

Human farnesyl pyrophosphate synthase (hFPPS) is the gate-keeper of mammalian isoprenoids and the key target of bisphosphonate drugs. Bisphosphonates suffer from poor "drug-like" properties and are mainly effective in treating skeletal diseases. Recent investigations have implicated hFPPS in various nonskeletal diseases, including Alzheimer's disease (AD). Analysis of single nucleotide polymorphisms in the hFPPS gene and mRNA levels in autopsy-confirmed AD subjects was undertaken, and a genetic link between hFPPS and phosphorylated tau (P-Tau) levels in the human brain was identified. Elevated P-Tau levels are strongly implicated in AD progression. The development of nonbisphosphonate inhibitors can provide molecular tools for validating hFPPS as a therapeutic target for tauopathy-associated neurodegeneration. A multistage screening protocol led to the identification of a new monophosphonate chemotype that bind in an allosteric pocket of hFPPS. Optimization of these compounds could lead to human therapeutics that block tau metabolism and arrest the progression of neurodegeneration.
