Pre-mRNA maturation frequently occurs at the same time and place as transcription by RNA polymerase II. The co-transcriptionality of mRNA processing has permitted the evolution of mechanisms that functionally couple transcription elongation with diverse events that occur on the nascent RNA. This review summarizes the current understanding of the relationship between transcriptional elongation through a chromatin template and co-transcriptional splicing including alternative splicing decisions that affect the expression of most human genes.
前体mRNA的成熟过程通常与RNA聚合酶II的转录过程在同一时间和地点发生。mRNA加工的共转录特性使得一些机制得以进化,这些机制在功能上将转录延伸与新生RNA上发生的各种事件联系起来。本综述总结了目前对于通过染色质模板进行的转录延伸与共转录剪接(包括影响大多数人类基因表达的可变剪接决定)之间关系的理解。
