title: Synthesis of chick brain GABA receptors by frog oocytes.
abstract: Poly(A)-mRNA, extracted from the optic lobe of chick embryos, directs the synthesis of gamma-aminobutyric acid (GABA) receptors in Xenopus laevis oocytes. The receptors are inserted into the oocyte membrane, where they form receptor--channel complexes. When activated by GABA, and related agonists, the chick brain receptors open membrane channels that are permeable to chloride ions. Thus, Xenopus oocytes provide a novel and useful approach to the study of brain receptors.
