MicroRNAs (miRNAs) are short (20–24 nt) noncoding RNAs that regulate gene expression post-transcriptionally in multicellular organisms by affecting mRNA stability and translation. They are transcribed by RNA polymerase II as parts of capped, polyadenylated primary transcripts (pri-miRNAs), which may be protein-coding or noncoding. Pri-miRNAs are cleaved by the RNase III enzyme Drosha to produce approximately 70-nt stem-loop precursor miRNAs (pre-miRNAs), which are further processed by cytoplasmic Dicer into mature miRNA and antisense miRNA* products. The mature miRNA is incorporated into the RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing and most often leads to translational repression or destabilization of the target mRNA. This RefSeq representative predicts a microRNA stem-loop.
