- Automated Description
- Enables mRNA 3'-UTR binding activity and mRNA base-pairing translational repressor activity. Involved in several processes, including regulation of cell migration involved in sprouting angiogenesis; regulation of gene expression; and regulation of signal transduction. Located in extracellular exosome. Implicated in atrophic gastritis; carcinoma (multiple); coronary artery disease; fatal familial insomnia; and type 1 diabetes mellitus. Biomarker of several diseases, including artery disease (multiple); arthritis (multiple); bacterial gastritis; hepatitis C; and systemic lupus erythematosus.
- RGD Description
- 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. Some of the targets of the encoded miRNA are the transcripts for tumor necrosis factor, interleukin 1 receptor-associated kinase 1, interleukin 1-beta, TNF receptor-associated factor 6, and complement factor H. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2015]
