Abstract
The relative abilities of 7 vasopressin-like peptides to activate [rat] hepatic glycogen phosphorylase and stimulate phosphate incorporation into phosphatidylinositol were compared. Although the individual peptides differed in their potencies, the concentrations required to stimulate phosphatidylinositol metabolism were always greater (about 10 times) than those needed to activate phosphorylase. The molecular specificity of the hepatic vasopressin receptor and the role of vasopressin-stimulated phosphatidylinositol turnover are discussed.This publication has 18 references indexed in Scilit:
