5.8S rRNA
在分子生物学中，5.8S核糖体RNA（5.8S rRNA)是指一类非编码RNA。它是真核生物核糖体的大亚基的组成成分，在蛋白质转译中起重要作用。RNA聚合酶I先转录出沉降系数为45S的前体。该前体同样包含18S rRNA和28S rRNA。5.8S rRNA在核糖体转运中起作用。它能够和p53肿瘤抑制蛋白形成共价连接。
5.8S rRNA可以作为探查miRNA的参考基因。

5.8S ribosomal RNA 5.8S rRNA
In molecular biology the 5.8S ribosomal RNA (5.8S rRNA) is a non-coding RNA component of the large subunit of the eukaryotic ribosome and so plays an important role in protein translation. It is transcribed by RNA polymerase I as part of the 45S precursor that also contains 18S and 28S rRNA. Its function is thought to be in ribosome translocation. It is also known to form covalent linkage to the p53 tumour suppressor protein.
