title: The nuclear localization of a putative neurotransmitter receptor.
abstract: A high affinity strychnine binding site has been identified within a membrane fraction prepared from partially purified rat brain nuclei. This interaction appears similar in its characteristics to that occurring in the non-nuclear membrane fraction which is thought to occur at the synaptic glycine receptor complex. Both the nuclear and non-nuclear membrane binding of tritiated strychnine is greater within the pons-medulla region than in the cerebral cortex. Nuclear membrane binding sites for dopamine, norepinephrine (beta-adrenergic), acetylcholine (muscarinic), GABA, and diazepam were not detected.
