典型的串联CCCH型锌指结构蛋白(tandem CCCH zinc finger proteins, TZFs)含有由18个氨基酸分隔的二个串联CCCH motifs(C-X_(7-8) -C-X_5 -C-X_3 -H、C-X_5 -C-X_4 -C-X_3 -H)。富含精氨酸的RR-TZF蛋白是植物特有,研究表明RR-TZF蛋白通过介导RNA的降解来调节基因的表达水平,影响植物的生长发育以及胁迫反应。本研究主要综述了植物RR-TZF蛋白在生长发育及胁迫反应中的功能及作用机制等;同时利用生物信息学手段对RR-TZF蛋白进行聚类分析,系统地分析了RR-TZF蛋白从低等植物到高等植物中的进化与保守性,并展望了未来可能的研究方向。为探究CCCH型锌指结构蛋白家族基因在作物中的具体功能及其应对非生...

The typical tandem CCCH zinc finger (TZF) protein contains two tandem CCCH motifs, C-X_(7-8) -C-X_5 - C-X_3 -H and C-X_5 -C-X_4 -C-X_3 -H, which are spaced by 18 amino acids. Arginine-rich TZF (RR-TZF) proteins are specific in plant. Researches showed that the expression level of genes were regulated through mediating RNA degradation by RR-TZF protein, as well as affected the plant growth and stress response. This review mainly summarized the functions and reaction mechanisms of plant RR-TZF proteins during growth, development and stress responses. Besides, clustering analysis was performed on...
