摘要/Abstract

摘要： PHD-finger 蛋白是一类广泛存在于真核生物中, 在基因转录和染色质状态调控方面有重要作用的锌指蛋白。目前在动物中对PHD-finger 蛋白的结构和功能方面的研究较为广泛和深入, 而在植物中仅有少数PHD-finger 蛋白的功能被阐明。通过SMART 和Pfam等数据库分析, 我们发现拟南芥中共有70 个PHD-finger蛋白, 其中大部分PHD-finger 蛋白的功能未知。本文通过生物信息学分析获得拟南芥PHD-finger 家族较为全面的信息, 包括基因结构、染色体定位、基因表达、蛋白结构域、系统进化关系等, 为深入研究PHDfinger家族蛋白的结构与功能提供了参考。

Abstract: PHD-finger proteins were found universally in eukaryotes and known as key players in regulating chromatin or transcription . In animals, many PHD-finger proteins had been well studied on structure and function . Compared to animals, only a few of plant PHD-finger proteins had been characterized functionally . By both SMART and Pfam searches, 70 members of the PHD-finger family were identified in Arabidopsis thaliana .Most of the PHD-finger proteins in Arabidopsis thaliana were functionally unknown . A complete overview of this family by bioinformatic approach were presented in this
paper , including the gene structure , gene localization in genome , gene expression , protein motif organization , and phylogenetic relationship of each family member . These results should provide useful information for the further structural and functional studies of PHD-finger proteins .
