Scope note: ARN bicatenarios pequeños, no codificadores de proteínas, con una longitud de 21-25 nucleótidos, que son formados a partir de transcritos génicos de microARN monocatenarios por la misma RIBONUCLEASA III, Dicer, que produce ARN INTERFERENTES PEQUEÑOS. Pasan a formar parte del COMPLEJO DEL SILENCIAMIENTO INDUCIDO POR EL ARN y reprimen la traducción (TRADUCCIÓN GENÉTICA) de determinados ARN mediante la unión a la región 3'UTR homóloga como apareamiento imperfecto. Los ARN temporales pequeños (stRNA), let-7 y lin-4, de C. elegans, son los 2 primeros miRNA descubiertos y pertenecen a la clase de miRNA implicados en la cronología del desarrollo.

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.
