Properties of human brain glycine receptors expressed in Xenopus oocytes.

Abstract
Glycine and gamma-aminobutyric acid (GABA) receptors from the foetal human brain were 'transplanted' into the Xenopus oocyte membrane by injecting the oocytes with poly(A)+-mRNA extracted from the cerebral cortex. Activation of both glycine and GABA receptors induced membrane currents carried largely by chloride ions. However, unlike the GABA-activated current, the glycine current was blocked by strychnine, and was not potentiated by barbiturate. At low doses, the glycine current increased with concentration following a 2.7th power relation, suggesting that binding of three molecules of glycine may be required to open a single membrane channel. The current induced by steady application of glycine decreased with hyperpolarization beyond about -60 mV.
