Involvement of GTP-binding proteins in angiotensin II-induced mobilization of calcium has been examined in adrenal glomerulosa cells by using pertussis toxin. Pretreatment of glomerulosa cells with pertussis toxin abolishes angiotensin II-induced calcium influx without blocking inositol trisphosphate production. These results suggest a role of the pertussis toxin-sensitive GTP-binding protein in transducing angiotensin II-receptor occupancy into opening of calcium channel.
