H-Ras does not need COP I- or COP II-dependent vesicular transport to reach the plasma membrane.

Abstract excerpt

Although vesicular transport of the H-Ras protein from the Golgi to the plasma membrane is well known, additional trafficking steps, both to and from the plasma membrane, have also been described. Notably, both vesicular and nonvesicular transport mechanisms have been proposed. The initial trafficking of H-Ras to the plasma membrane was therefore examined in more detail. In untreated cells, H-Ras appeared at the...
