MicroRNAs (miRNAs) are short (20–24 nucleotide) noncoding RNAs involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting mRNA stability and translation. miRNAs are transcribed by RNA polymerase II as capped and polyadenylated primary transcripts (pri-miRNAs), which can be protein-coding or noncoding. The primary transcript is cleaved by the RNase III enzyme Drosha to produce an approximately 70-nucleotide stem-loop precursor miRNA (pre-miRNA), which is further cleaved by cytoplasmic Dicer to yield mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into the RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing and most commonly causes translational inhibition or destabilization of the target mRNA. RefSeq represents the predicted microRNA stem-loop. [Provided by RefSeq, Sep 2009]
