摘　　要：根据GYF结构域蛋白质分布的广泛性及功能的多样性,更深入地研究GYF结构域蛋白,并对其进行进化分析是十分必要的。因AtEXA1是植物里研究最为透彻的GYF结构域蛋白,因此,本研究主要聚焦于与AtEXA1类似的蛋白的研究。通过分析真核生物(范围从单细胞低等真菌到高等生物)中的8053个GYF结构域蛋白,研究发现类似AtEXA1的蛋白质主要存在于植物物种中,而来自动物的GYF蛋白质与AtEXA1的相似性较低。研究还发现,类似AtEXA1的蛋白质存在于几乎所有的农作物中。本研究展示了GYF结构域蛋白的保守性,初步解构了GYF结构域蛋白进化的历程,并为后续对GYF结构域蛋白功能特征的研究提供了启示。According to the extensive distribution of GYF domain proteins and the diversity of its functions,it is necessary to study GYF domain proteins further and conduct evolutionary analysis.Since AtEXA1 is the most well-studied GYF domain protein in plants,this study mainly focuses on the proteins similar to AtEXA1.Analysis of 8053 GYF domain proteins in eukaryotes ranging from unicellular lower fungi to higher organisms showed that AtEXA1-like proteins are mainly found in plant species,while GYF proteins from animals have low similarity to AtEXA1.It was also found that AtEXA1-like proteins are present in almost all agricultural crops.This study demonstrates the conservation of all GYF domain proteins,initially deconstructs the evolution of GYF domain proteins,and provides implications for subsequent studies on the functional characteristics of GYF domain proteins.
