以类似与靶向特异性等位基因的模式,RNAi可用于除去内源等位基因以达到用转基因代替的目的.这重方法等于针对MRNA的非翻译区的DSRNA具有的抑制基因表达的能力.这就不需要靶向编码序列即可去除内源基因的表达.突破的等位基因由于缺乏靶向作用而不受内源野生型等位基因的影响.
在另一相关的方法中,一种带有表位标签的等为基因可在通过靶向非翻译区而缺失了内源蛋白质表达的细胞进行表达.这方法具有作为蛋白质组学研究工具的潜在价值.列如,在方法曾用语缺失果蝇的内源性外体(exosome)组分中的 RRP4,同时导入人类同源基因的带标签等位基因,因此极大地促进了将标签蛋白掺入内源性外提蛋白质复合体的效率.直接针对标签的亲和纯化即可产生非常纯净的内源性外蛋白组分.此时,靶向基因被同源基因代替;但是通过靶向非翻译区,可再次引入同一基因.

Targeting a specific allele with similar models, RNAi can be used to remove the source of alleles to meet with transgenic substitute purposes. Equivalent method against this heavy-untranslated region MRNA the DSRNA with the ability to inhibit gene expression. This does not require coding sequence can be removed targeting endogenous gene expression. allele due to the lack of a breakthrough role without targeting endogenous wild-type allele effects.
In a related way, with an epitope tagged as the gene can be targeted through non-untranslated region and the lack of endogenous protein expression in cells expression. As this method has the potential of proteomics research tools value. out if, in the way the term has been the lack of endogenous Drosophila outside body (exosome) component of RRP4, while the homologous gene into human allele with labels, it will greatly promote the labeling protein-doped mention of the endogenous protein complexes efficiency. directly address label af
