Isoprenoid modification and plasma membrane association: critical factors for ras oncogenicity.

Abstract

Association of ras protein with the plasma membrane is critical for its transforming activity. This association is promoted by a series of post-translational modifications that are signaled by the consensus C-terminal CAAX motif present in all ras proteins. The recent discovery that a 15-carbon isoprenoid (farnesyl) group, derived from an essential intermediate in cholesterol biosynthesis, is attached covalently to ras proteins has stimulated considerable interest and has suggested several important new directions for ras studies. In particular, one promising pharmacologic approach for antagonizing oncogenic ras activity in human malignancies would be to design specific inhibitors of the enzymes that catalyze ras processing and thereby interfere with ras protein association with the plasma membrane.
