The observed homology between G-proteins which regulate adenylate cyclase and ras proteins and the suggested role of ras in the regulation of adenylate cyclase in yeast prompted us to examine the regulation of adenylate cyclase in three cell lines: (i) NIH 3T3 cells, (ii) NIH 3T3 cells transformed by high levels of the normal rasH gene product and (iii) NIH 3T3 cells transformed by a mutated rasH gene product. We found that the regulation of adenylate cyclase by G-proteins is identical in the three cell lines, although the response of the transformed NIH 3T3 cells to agonists is strongly attenuated. Our data suggest that mammalian ras products do not interact directly with adenylate cyclase, although their increased expression may indirectly inhibit the interaction of adenylate cyclase stimulatory receptors with G-proteins.
