21-23个核苷酸的单链RNA被归类为microRNAs(MiRNA),在广泛的细胞和发育过程中发挥着基础作用。MiRNAs通过与靶信使RNAs的序列特异性碱基配对来调节蛋白质的表达,降低了它们的稳定性和蛋白质翻译的过程。至少30%的蛋白质编码基因似乎是miRNAs的保守靶标。与蛋白质编码基因相比,不存在miRNA小鼠突变等位基因的公共资源。我们已经建立了一个高度生殖系可传递的C57BL/6N小鼠突变胚胎干细胞(ES)的文库,其中针对目前在miRBase注册表中注释的大多数miRNA基因进行了定向缺失。这些等位基因被设计成高度适应性的研究工具,可以有效地改变以创建报告、条件和其他等位基因变体。这种ES细胞资源可以通过电子方式进行搜索,并可从ES细胞储存库中获得,以便分发给科学界。
The 21-23 nucleotide single-stranded RNAs classified as microRNAs (miRNA) perform fundamental roles in a wide range of cellular and developmental processes. miRNAs regulate protein expression through sequence-specific base pairing with target messenger RNAs (mRNA) reducing both their stability and the process of protein translation. At least 30% of protein coding genes appear to be conserved targets for miRNAs. In contrast to the protein coding genes, no public resource of miRNA mouse mutant alleles exists. We have generated a library of highly germ-line transmissible C57BL/6N mouse mutant embryonic stem (ES) cells with targeted deletions for the majority of miRNA genes currently annotated within the miRBase registry. These alleles have been designed to be highly adaptable research tools that can be efficiently altered to create reporter, conditional and other allelic variants. This ES cell resource can be searched electronically and is available from ES cell repositories for distribution to the scientific community.
