摘要
In eukaryotes,most protein-coding genes contain introns which are removed by precursor messenger RNA(pre-mRNA) splicing.Alternative splicing is a process by which multiple messenger RNAs(mRNAs) are generated from a single pre-mRNA,resulting in functionally distinct proteins.Recent genome-wide analyses of alternative splicing indicated that in higher eukaryotes alternative splicing is an important mechanism that generates proteomic complexity and regulates gene expression.Mis-regulation of splicing causes a wide range of human diseases.This review describes the current understanding of pre-mRNA splicing and the mechanisms that regulate mammalian pre-mRNA splicing.It also discusses emerging directions in the field of alternative splicing.
