Fig. 6: 1984 model of adenylyl cyclase susceptible to both stimulatory and
inhibitory regulation through the respective heterotrimeric stimulatory (N,,
now G,) and inhibitory (N; now Gj) regulatory components. Each G protein was
shown to be under the control of a distinct set of receptors responsible for
distinct hormonal specificities exhibited by adenylyl cyclases from different
tissues and cells. (From Hildebrandt et al. 1984)
