启动子结构和功能研究进展

摘要

Gene expression and its regulation are dependent, on to a great extent, on transciption. An elementary transciption reaction is initiated by the recognition of regulatory regions and especially promoters. Promoters is the cis-regulatory element of gene expression and its regulation, exsit in eukaryotes and prokaryotes. This paper expounded on the general characteristics and the function of promoter segment and cis-element functions.%转录起始是一种最重要的表达调节方式，通过多种蛋白质与启动子的配位结合起始转录，参与基因的表达调控过程。而启动子作为基因表达调控的重要顺式作用原件，在原核和真核生物中均存在。对核心启动子结构特征中多种保守顺式调控原件及基本转录因子的结构和功能进行了阐述。
