Abstract

Ral GDP dissociation stimulator (Ral GDS) has been found to be an effector protein of Ras, and Ral, a member of small GTP-binding protein (G protein) superfamily, has been suggested to act downstream of Ras. Ral GDP dissociation stimulator-like (RGL) shares 50% amino acid identity with Ral GDP dissociation stimulator, and assumed to possess similar functional role. Using yeast two-hybrid screening, we found that dopamine D3 receptor interacts with RGL. Since RGL is known to regulate the expression of c-fos promoter, effects of D3R on gene expression of c-fos promoter was studied. (omitted)
