microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]
[中文简述(自动翻译):] 微RNA（miRNAs）是短（20-24核苷酸）非编码由既影响稳定性和mRNA的翻译参与基因表达的转录后调控在多细胞生物体的RNA。的miRNA通过RNA聚合酶II转录为加盖并聚腺苷酸化初级转录物的部分（PRI-微RNA），可以是任一蛋白质编码或非编码。初级转录由酶Drosha核糖核酸酶III酶裂解以产生约70个核苷酸茎 - 环前体miRNA（前miRNA），这是由胞质Dicer的核糖核酸酶进一步切割以产生成熟miRNA和反义miRNA的星（miRNA的* ）产品。成熟miRNA掺入RNA诱导的沉默复合物（RISC），其通过不完全碱基配对识别靶mRNA与所述miRNA和最通常导致翻译抑制或去稳定化的靶mRNA。所述的RefSeq表示预测的微RNA茎环。 [由RefSeq的，2009年09月提供]
