Study on Recombinant Expression of Human ARF1 and Interactions between ARF1 and Small Molecules

Abstract

腺苷酸核糖基化因子(ADP-ribosylationfactor,ARF)是小G蛋白大家庭的一员,广泛分布于真核细胞中,并且其结构和功能在物种进化过程中高度保守。其中,ARF1作为ARF蛋白家族总量最大、分布最广的蛋白,在各种细胞中通过与高尔基体相互作用,发挥着协助细胞物质运输的功能,影响着各种疾病的发生发展。 本研究采用分子克隆的方法成功构建人类腺苷酸核糖基化因子1(humanADP-ribosylationfactor1,简称hARF1)重组质粒pET28a(+)-hARF1,并在大肠杆菌BL21(DE3)中优化表达hARF1蛋白。经Ni2+亲和层析柱和葡聚糖凝胶柱纯化,通过SDS-PA...ADP-ribosylation factor ((ADP-ribosylation factor, ARF) is a kind of small GTP-binding proteins, which is widely distributed in eukaryotic cells. Its structure and function are highly conserved during species evolution. ARF1 interacts with Golgi apparatus and plays the role of regulator of vesicle trafficking, affecting the development of various diseases. In this thesis, recombinant plasmid...学位:理学硕士院系专业:化学化工学院化学系_化学生物学学号:2052008115176
