摘要
Ran是一类在多种基本细胞活动中扮演者重要角色的小GTP酶。从香蕉基因组中鉴定出9个MuRan家族基因成员,并对其染色体分布、基因结构、蛋白理化性质、结构域和系统进化等进行分析。结果表明:MuRan家族基因不均匀的分布在第1、4、5、6号等4条染色体上。MuRan蛋白与其它植物Ran蛋白的氨基酸序列都有很高的同源性,带有GTP水解结构域、Ran GAP结合结构域和酸性尾巴等Ran蛋白的典型结构域,与拟南芥AtRan蛋白亲缘关系较近。为进一步研究香蕉MuRan家族基因的生物学功能提供参考。
Ran is a kind of small GTPases that plays an important role in fundmental cellular activities.In the present study,9 MuRan family genes were identified in banana genome and their chromosome distribution,gene structure,physical and chemical characteristics,function domain and evolutionary relationship were analyzed.The results indicated that MuRan family genes were evenly distributed in 4 chromosomes.MuRan proteins showed high homology with Ran proteins from other plants and contained characteristic domains of Ran proteins,including GTP Hydrolysis domain,Ran GAP- binding domain and acidic tail and were relatively closer with AtRan in phylogenetic relationship.
