Anterior pituitary adenylate cyclase: stimulation by dopamine and other monoamines.
Adenylate cyclase activity of homogenates of anterior pituitary from rat, rabbit and monkey was stimulated by dopamine, other amine neurotransmitters and Gpp(NH)p. The concentration of dopamine for half-maximal stimulation of activity was 2--5 micrometer. Studies with selective agonists and antagonists indicated the presence of dopamine receptors and beta-adrenergic receptors coupled to adenylate cyclase in anterior pituitary. In addition, histamine stimulated activity in rabbit and monkey, but not in rat, anterior pituitary.
