Although the definition of a noncoding RNA (ncRNA) is an RNA molecule that does not encode a protein, recent evidence has revealed that some ncRNAs are indeed translated to give rise to small polypeptides (usually containing fewer than 100 amino acids). Despite their small size, however, these peptides are often biologically relevant in that they are required for a variety of cellular processes. In this review, we summarize the production and functions of peptides that have been recently identified as translation products of putative ncRNAs.Key words: long noncoding RNA (lncRNA), circular RNA (circRNA), primary miRNA (pri-miRNA), translation, peptide.

假定的非编码RNA编码的隐藏肽。

尽管非编码RNA（ncRNA）的定义是不编码蛋白质的RNA分子，但最近的证据表明，某些ncRNA确实经过翻译产生了小的多肽（通常包含少于100个氨基酸）。尽管它们的体积很小，但是这些肽通常在生物学上是相关的，因为它们是多种细胞过程所必需的。在这篇综述中，我们总结了最近被鉴定为推定ncRNA的翻译产物的肽的产生和功能。关键词：长非编码RNA（lncRNA），环状RNA（circRNA），初级miRNA（pri-miRNA），翻译，肽。
