We have previously identified proteolytic activity in rat liver microsomes that cleaves an intact tripeptide, VIS, from S-farnesylated-CVIS tetrapeptide. This enzymatic activity, termed prenyl protein-specific endoprotease (PPEP) activity, has been solubilized in CHAPS and purified 5-fold. To probe the peptide recognition features of PPEP activity, 64 tripeptides [N-acetyl-C(S-farnesyl)a1a2] we...
Earlier studies (Rilling, H. C. (1972) Biochem. Biophys. Res. Commun. 46, 470-475) suggested the possibility that a sterol carrier protein participated in the enzymatic conversion of farnesyl pyrophosphate to squalene by liver microsomal membranes. In the present article the possible requirement for soluble proteins in liver 105,000 x g supernatant (Slos) in the enzymatic conversion of farnesyl...
Farnesyl transferase inhibitors (FTI) exhibit anticancer activity as a single agent in preclinical studies and show promise in combination with other therapeutics in clinical trials. Previous studies show that FTIs arrest cancer cells in mitosis; however, the mechanism by which this occurs is unclear. Here, we observed that treatment of various cancer cell lines with the FTI lonafarnib caused m...
Among the most important targets for chemopreventive intervention and drug development are deregulated signal transduction pathways. Ras proteins serve as central connectors between signals generated at the plasma membrane and nuclear effectors; thus, disrupting the Ras signaling pathway could have significant potential as a cancer chemopreventive strategy. Target organs for Ras-based chemoprev...
