框H/ACA snoRNAs代表了一组丰富的小非编码rna,主要参与真核生物和古细菌中RNAs和/或snrna的假尿嘧啶化。在这项研究中,我们描述了一种新的实验方法来系统地鉴定真核生物中的box H/ACA snoRNAs。在用该方法构建的含人血细胞总rna的特异性cDNA文库中,实现了对多种box H/ACA snoRNA的高效克隆,并首次从人体内鉴定出该家族的7个新种。此外,该方法已成功地应用于果蝇和裂变酵母的box H/ACA snoRNAs的鉴定,显示了在广泛的真核生物中对box H/ACA snoRNAs进行系统分析的强大能力。
Box H/ACA snoRNAs represent an abundant group of small non-coding RNAs mainly involved in the pseudouridylation of rRNAs and/or snRNAs in eukaryotes and Archaea. In this study, we describe a novel experimental method for systematic identification of box H/ACA snoRNAs from eukaryotes. In the specialized cDNA libraries constructed by this method with total cellular RNAs from human blood cells, the high efficiency of cloning for diverse box H/ACA snoRNAs was achieved and seven novel species of this snoRNA family were identified from human for the first time. Furthermore, the novel method has been successfully applied for the identification of the box H/ACA snoRNAs from Drosophila and the fission yeast, demonstrating a powerful ability for systematic analysis of box H/ACA snoRNAs in a broad spectrum of eukaryotes.
