MeSH Heading: MicroRNAs
Tree Number(s): D13.150.650.319; D13.444.735.150.319; D13.444.735.790.552.500
Unique ID: D035683
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D035683
Scope Note: Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.
