植物亲环素基因功能研究进展

Research Progress of Plant Cyclophilin Gene Functions

亲环素属于亲免素家族,具有肽基脯氨酰顺反异构酶(PPIase)活性,在生物界广泛分布,存在于细胞质和各个细胞器中,且在结构上高度保守。植物亲环素是一个多基因家族,除具有一般亲环素的功能外,还在一系列生物学过程中发挥重要作用,如参与胁迫应答、代谢调控及植物的生长发育等。该文主要对近年来国内外有关植物亲环素基因的功能和研究进展进行综述,为今后亲环素研究提供参考。

Cyclophilins（CyPs）,members of the ‘immunophilin＇protein family,have peptidyl-prolylcistrans isomerase activity and widely distribute in different organisms.They are highly conserved in protein structure and expressed in cytosol and various organelles.Plant CyPs are supper-family members and play significant roles in stress response,metabolic regulation and plant development besides their common functions.This review summarizes the functions and recent research progress of plant CyPs and aims to help their further characterization in the future.
