Abstract

The capacity of membranes from the ovaries, oviducts and uteri of rats to bind [35S]t-butylbicydo-phosphorothionate (TBPS), and the effect of γ-aminobutyric acid (GABA) and pentobarbital on the specific binding of TBPS were examined. Specific TBPS binding, that could be modulated by GABA and pentobarbital in an allosteric manner, was demonstrated. These findings indicate that the TBPS-labeled chloride ion channels in the female sex organs are regulated by GABA and pentobarbital sites, in a fashion similar to that observed In the brain.
