Alternative splicing of mRNA precursors provides an important means of genetic control and is a crucial step in the expression of most genes. Alternative splicing markedly affects human development, and its misregulation underlies many human diseases. Although the mechanisms of alternative splicing have been studied extensively, until the past few years we had not begun to realize fully the diversity and complexity of alternative splicing regulation by an intricate protein-RNA network. Great progress has been made by studying individual transcripts and through genome-wide approaches, which together provide a better picture of the mechanistic regulation of alternative pre-mRNA splicing.
mRNA前体的可变剪接提供了一种重要的基因调控方式,并且是大多数基因表达过程中的关键步骤。可变剪接显著影响人类发育,其调控异常是许多人类疾病的根源。尽管可变剪接的机制已得到广泛研究,但直到过去几年,我们才开始充分认识到由复杂的蛋白质-RNA网络调控可变剪接的多样性和复杂性。通过研究单个转录本以及全基因组方法已经取得了巨大进展,这些研究共同为前体mRNA可变剪接的机制调控提供了更清晰的图景。
