用非竞争性抑制剂[~3H]叠氮杂环鸟碱对加州鱼雷和马纹伊蚊电子组织富含受体的膜上的烟碱型乙酰胆碱受体进行了光标记。用十二烷基硫酸钠-聚丙烯酰胺凝胶分离受体亚基,从凝胶中回收α-亚基,用金黄色葡萄球菌V8蛋白酶切。用125I标记的α-银环蛇毒素结合蛋白印迹和刀豆蛋白A染色鉴定蛋白降解片段。在没有氨基甲酰胆碱和氨甲酰胆碱存在的情况下,观察到V8-18 kDa片段的标记。在这里使用的两种鱼雷都发现了这一点。
Nicotinic acetylcholine receptors in receptor-rich membranes from Torpedo californica and from T. marmorata electric tissue were photolabeled with the non-competitive inhibitor [3 H] azidophencyclidine. The receptor subunits were separated on SDS-polyacrylamide gels and the α-subunits recovered from the gel, were subjected to Staphylococcus aureus V8 protease cleavage. The proteolytic fragments were resolved by SDS-polyacrylamide gel electrophoresis and were identified on protein blots by 125 I-labeled α-bungarotoxin binding and by staining with concanavalin A. The site of specific azidophencyclidine labeling has been localized to the V8–18 kDa fragment which binds toxin. Labeling of the V8–18 kDa fragment was observed in the absence and in the presence of carbamylcholine. This was found for both the species of Torpedo used here.
