摘要:

Pirins(简称PRNs、PIRs)是含有Cupin结构域的基因家族,属于功能各异的Cupin超家族成员之一。PRN蛋白的N端结构域含有金属离子结合位点,在原核和真核生物中高度保守。人hPRN可作为转录因子辅因子和氧化还原感受器参与癌症发生过程,是癌症治疗的潜在靶点。植物PRNs基因家族一般含有多个成员,其生物学功能尚未得到深入研究。概述了PRNs蛋白的基本结构及其生化特征,并综述了PRNs在人、微生物和植物中的生物学功能,以期为进一步解析水稻等作物中PRNs的功能提供一定线索,并为基因编辑等生物育种技术改良作物提供新的靶点。

Abstract:

Pirins (PRNs, PIRs) are gene family containing cupin domain and belong to the functionally diversity cupin superfamily. The N-terminal domain of PRN contains a metal-ion binding site, which is highly conserved in prokaryotes and eukaryotes. Human hPRN could participate in cancer development as transcriptional regulator and redox sensor, suggesting that hPRN is a potential therapeutic target. In plants, there are several members in PRNs gene family, whereas their biological functions remain largely unknown. This paper outlined the basic structure and biochemical characteristic of PRNs, and reviewed the biological research progresses in human, microorganism and plants, in order to provide clues to clarify the PRNs molecular mechanism of crop such as rice, and provide target genes for the genetic improvement of crops production or adapation by gene editing and other molecular breeding techniques.

Key words: PRNs gene family, metal ions, transcriptional regulator, redox sensor, target
