Abstract
Polyclonal antibodies were raised in rabbits against the GABAA-receptor beta 3 subunit peptide sequence, KQSMPREGHGRHMDR-NH2 coupled to keyhole limpet haemocyanin. These anti-beta 3 379-393 antibodies immunoprecipitated in a dose-dependent manner specific benzodiazepine agonist binding sites from Na+ deoxycholate extracts of bovine cerebral cortex. In immunoblots, anti-beta 3 379-393 antibodies recognised two species with Mr 59,900 and Mr 57,200 in all preparations tested, which included crude detergent-solubilised, benzodiazepine affinity chromatography-purified receptor, anti-alpha 1 324-341 antibody, anti-Cys alpha 2 414-424 antibody and anti-Cys alpha 3 454-467 antibody immunoaffinity-purified GABAA-receptor subpopulations. These results provide evidence for the ubiquity and promiscuity of the GABAA-receptor beta 3 subunit.
