WebApr 1, 2003 · HDJ-2 farnesylation (mean +/- SD) decreased by 33.4% +/- 19.8% on day 15. Conclusion: Although treatment with R115777 resulted in partial inhibition of FTase activity in mononuclear cells, it did not exhibit single-agent antitumor activity in patients with previously untreated metastatic pancreatic cancer. WebFarnesyltransferase. FTase is a heterodimer containing an α and a β subunit (48 and 46 KDa, respectively) in mammalian cells. The activity of FTase requires both Zn 2+ and Mg 2+ [46]. FTase can bind to farnesyl pyrophosphate (FPP) and peptide substrate independently. The β subunit of FTase binds to FPP with a very high affinity without ... town of mansfield ct town manager
