صينى. 细菌需要复杂而精密的信号系统来应对体内外环境变化，从而适应环境并得以生存。双组分系统（two component system, TCS）广泛存在于原核生物细胞中，由组氨酸激酶（histidine kinase，HK）和反应调控蛋白（response regulator，RR）组成，通过双组分蛋白的磷酸化和去磷酸化调节细胞信号传导途径。介绍了双组分系统的结构、反应机制和功能等方面研究进展，并探讨了双组分系统在细胞信号传导中的作用。

Two component systems are abundant in prokaryotes, which consist of a histidine kinase (HK) and a response regulator (RR). They regulate cellular signal transduction pathway, according to phosphorylation and dephosphorylation. This review mainly introduces the progress made in structure, mechanism and function research, and explores the role of two component systems in cell signal transduction.
