title: Neurotransmitter receptor interactions with G-proteins: a critical link in receptor response mechanisms.
abstract: The interaction of membrane bound receptors with guanine nucleotide binding regulatory proteins is necessary for the transduction of many extracellular signals across the cell membrane. Age-related impairments of this interaction illustrate that the efficiency of receptor effector coupling is complex, and is an additional factor for consideration in the future study of receptor mediated functions.
