Characterization of a GTPase-activating protein for the Ras-related Ral protein.

Abstract excerpt

We have demonstrated the presence of a GTPase-activating protein (GAP) for the Ras-related Ral A protein in the cytosolic fraction of brain and testis. This protein, designated Ral-GAP, was distinguished from Ras-GAP by its behavior in two chromatography systems and by the fact that the two GAP proteins did not stimulate the GTPase activity of each others target GTP binding proteins. The lack of effect of Ral-GAP...
