对果蝇碱基(Ine)基因缺陷突变体的行为和电生理研究表明,运动神经元的兴奋性增加。本文介绍了该基因的克隆和序列分析。通过对突变株的限制性内切酶图谱和限制性片段长度多态性(RFLP)图谱分析,将突变基因定位在克隆DNA上。通过对发育中胚胎的转录物进行原位杂交,发现该基因在后肠、马氏管、肛板、花环细胞和中枢神经系统细胞亚群中均有表达。TheinecDNA包含一个658个氨基酸的开放阅读框架,与Na+/Cl−依赖的神经递质转运蛋白家族成员具有高度的序列相似性。这个家族的成员催化释放到突触的神经递质的快速再摄取,从而在控制神经元功能方面发挥关键作用。我们的结论是,诱变引起果蝇运动神经元兴奋性增加,其机制是引起果蝇运动神经元底物神经递质的再摄取缺陷,从而过度刺激运动神经元。从这一观察中获得了一个独特的机会,可以对果蝇运动神经元兴奋性的调节进行遗传解剖。
Behavioral and electrophysiological studies on mutants defective in theDrosophilainebriated (ine) gene demonstrated increased excitability of the motor neuron. In this paper, we describe the cloning and sequence analysis ofine. Mutations ininewere localized on cloned DNA by restriction mapping and restriction fragment length polymorphism (RFLP) mapping ofinemutants. DNA from theineregion was then used to isolate aninecDNA.In situhybridization ofinetranscripts to developing embryos revealed expression of this gene in several cell types, including the posterior hindgut, Malpighian tubules, anal plate, garland cells, and a subset of cells in the central nervous system. TheinecDNA contains an open reading frame of 658 amino acids with a high degree of sequence similarity to members of the Na+/Cl−-dependent neurotransmitter transporter family. Members of this family catalyze the rapid reuptake of neurotransmitters released into the synapse and thereby play key roles in controlling neuronal function. We conclude thatinemutations cause increased excitability of theDrosophilamotor neuron by causing the defective reuptake of the substrate neurotransmitter of theinetransporter and thus overstimulation of the motor neuron by this neurotransmitter. From this observation comes a unique opportunity to perform a genetic dissection of the regulation of excitability of theDrosophilamotor neuron.
