CeR-2 RNA是新发现的秀丽隐杆线虫非编码RNA(ncRNA)。通过RNomic研究对CeR-2的表征未能将其分类到任何已知的ncRNA家族中。在这项研究中,我们研究了时空表达模式的CeR-2,以了解其功能。CeR-2在从早期胚胎到成体阶段的大多数细胞中表达。这种RNA的亚细胞定位类似于核仁的主要蛋白质原纤蛋白。据观察,敲低C/D小核仁核糖核蛋白(snoRNP),而不是H/ACA snoRNP,导致CeR-2 RNA的异常核仁定位。与野生型菌株N2相比,细胞CeR-2 RNA量减少的突变体蠕虫显示其前rRNA加工模式的变化。这些结果表明,CeR-2 RNA是一个C/D snoRNA参与加工的rRNA。
CeR-2 RNA is one of the newly identified Caenorhabditis elegans noncoding RNAs (ncRNAs). The characterization of CeR-2 by RNomic studies has failed to classify it into any known ncRNA family. In this study, we examined the spatiotemporal expression patterns of CeR-2 to gain insight into its function. CeR-2 is expressed in most cells from the early embryo to adult stages. The subcellular localization of this RNA is analogous to that of fibrillarin, a major protein of the nucleolus. It was observed that knockdown of C/D small nucleolar ribonucleoproteins (snoRNPs), but not of H/ACA snoRNPs, resulted in the aberrant nucleolar localization of CeR-2 RNA. A mutant worm with a reduced amount of cellular CeR-2 RNA showed changes in its pre-rRNA processing pattern compared with that of the wild-type strain N2. These results suggest that CeR-2 RNA is a C/D snoRNA involved in the processing of rRNAs.
