Xist是哺乳动物X染色体失活的主要调节因子,是一种17 kb的lncRNA,顺式作用,使其转录的染色体上沿着的大多数基因沉默。Xist RNA功能所需的两个关键过程,顺式定位和沉默因子的募集,至少在部分上是遗传上可分离的。最近的研究已经确定了Xist RNA序列和相关的RNA结合蛋白(RBP),这对这些过程很重要。值得注意的是,几个关键的Xist RNA元件对应于局部串联重复序列。在这篇综述中,我用例子来说明不同的模式,串联重复扩增已被利用,让正统的RBP赋予新的功能XIST介导的染色体失活。我进一步讨论了潜在的一般性串联重复扩增功能长非编码RNA(lncRNA)的进化。
Xist, the master regulator of the X chromosome inactivation in mammals, is a 17 kb lncRNA that acts in cis to silence the majority of genes along the chromosome from which it is transcribed. The two key processes required for Xist RNA function, localisation in cis and recruitment of silencing factors, are genetically separable, at least in part. Recent studies have identified Xist RNA sequences and associated RNA-binding proteins (RBPs) that are important for these processes. Notably, several of the key Xist RNA elements correspond to local tandem repeats. In this review, I use examples to illustrate different modes whereby tandem repeat amplification has been exploited to allow orthodox RBPs to confer new functions for Xist-mediated chromosome inactivation. I further discuss the potential generality of tandem repeat expansion in the evolution of functional long non-coding RNAs (lncRNAs).
