Homologous structures of nuclear and GTPase-linked plasma membrane receptors suggest analogous mechanisms of action.
The molecular structures of nuclear and GTPase-linked plasma membrane receptors are compared here in the light of a recent finding suggesting that histone H1 may be an ATP/GTPase involved in transduction of the action of nuclear receptors. Considerable homology and conservation of the regions responsible for the interaction of the plasma membrane receptors with GTPases was observed in the nuclear receptors, thus suggesting analogous mechanisms of action and a common evolutionary origin for the two receptor families.
