Targeting of K-Ras 4B by S-trans,trans-farnesyl thiosalicylic acid.

Abstract excerpt

Ras proteins regulate cell growth, differentiation and apoptosis. Their activities depend on their anchorage to the inner surface of the plasma membrane, which is promoted by their common carboxy-terminal S-farnesylcysteine and either a stretch of lysine residues (K-Ras 4B) or S-palmitoyl moieties (H-Ras, N-Ras and K-Ras 4A). We previously demonstrated dislodgment of H-Ras from EJ cell membranes by...
