GABAA receptors with functional benzodiazepine receptors have been reconstituted by coexpression of alpha-, beta- and gamma-subunit cDNAs. In brain, proteins of the alpha- and beta-subunits, but not the gamma 2-subunit have been identified. Using an antipeptide antiserum, we now demonstrate that the gamma 2-subunit is a protein of 43 kDa. It is present in at least 50% of GABAA receptors, as shown by immunoprecipitation.
通过共表达α、β和γ亚基的互补DNA,已成功重构出具有功能性苯二氮䓬受体的GABAA受体。在大脑中,已鉴定出α和β亚基的蛋白质,但未鉴定出γ2亚基的蛋白质。利用抗肽抗血清,我们现在证明γ2亚基是一种43 kDa的蛋白质。免疫沉淀结果显示,它存在于至少50%的GABAA受体中。
