Abstract

The Argonaute proteins, which are the direct partners of the small RNAs involved in RNA interference mechanisms, can be divided into two subfamilies, the Argonautes and the Piwis. In animals, the Argonaute subfamily binds 21-22 nucleotide small interfering RNAs (siRNAs) and microRNAs (miRNAs), which direct cleavage and translational inhibition of their target RNAs respectively. The partners of the Piwi proteins are 24-30-nucleotide small RNAs called Piwi-interacting RNAs or piRNAs. In Drosophila, Piwi proteins and piRNAs protect the genome of the germline against selfish elements. Recent studies suggest that this function is conserved in mammals.La famille des Argonautes, les partenaires directs des petits ARNs dans les mecanismes d'interference par l'ARN, se divise en deux sous-groupes : les Argonautes et les Piwis. Chez les animaux, le sous-groupe des Argonautes se lie aux petits ARNs interferents (siARNs) et aux microARNs (miARNs) qui mesurent 21-22 nucleotides et sont responsables du clivage et de l'inhibition traductionnelle des ARNs cibles respectivement. Les proteines Piwis ont pour partenaires de petits ARNs de 24-30 nucleotides appeles Piwi-interacting RNAs ou piARNs. Chez la drosophile, les proteines Piwi et les piARNs protegent le genome de la lignee germinale contre les elements mobiles. Des analyses recentes suggerent que cette fonction est conservee chez les mammiferes.
