摘要:

反式剪接(trans-splicing,TS)是指两个或两个以上pre-mRNA分子经过剪接形成一个成熟mRNA的过程,是一种在转录后水平产生嵌合RNAs的方式。TS研究起步较晚,但高通量测序和生物信息学技术的发展,为相关研究提供了有效手段。伴随着大量TS及其嵌合RNAs被鉴定,人们发现TS可以产生新的功能性产物——融合蛋白或调控性非编码RNA,也可以仅仅通过竞争性使用亲本基因的pre-mRNA而影响亲本基因表达,从而在生理活动、疾病发生中发挥作用。本文就TS定义、类型、产生机制及其在哺乳动物中的作用等方面进行综述,以期为人们全面了解TS的研究概况及发展趋势提供参考。

Abstract:

Trans-splicing(TS) is the process by which two or more pre-mRNA molecules are spliced to form a mature mRNA, a way to produce chimeric RNAs at the post-transcriptional level. TS research started late, but the development of high-throughput sequencing and bioinformatics technologies has provided the effective means for related research. Along with the identification of a large number of TS and its chimeric RNAs, it has been found that TS can produce new functional products-fusion proteins or regulatory non-coding RNAs, also can affect parental genes expression only by competitive use of the parental pre-mRNA, which play important role in physiological activities and diseases. This article reviews the TS definition, type, production mechanism and its role in mammals, in order to provide a reference for completely understanding the research situation and development trend of TS.
