Tbio | Protein argonaute-3 |
Required for RNA-mediated gene silencing (RNAi). Binds to short RNAs such as microRNAs (miRNAs) and represses the translation of mRNAs which are complementary to them. Lacks endonuclease activity and does not appear to cleave target mRNAs. Proposed to be involved in stabilization of small RNA derivates (riRNA) derived from processed RNA polymerase III-transcribed Alu repeats containing a DR2 retinoic acid response element (RARE) in stem cells and in the subsequent riRNA-dependent degradation of a subset of RNA polymerase II-transcribed coding mRNAs by recruiting a mRNA decapping complex involving EDC4.
This gene encodes a member of the Argonaute family of proteins which play a role in RNA interference. The encoded protein is highly basic, contains a PAZ domain and a PIWI domain, and may play a role in short-interfering-RNA-mediated gene silencing. This gene is located on chromosome 1 in a tandem cluster of closely related family members including argonaute 4 and eukaryotic translation initiation factor 2C, 1. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

24100239 | Study uncovers a first example of a vertebrate protein factor, Argonaute-3, specifically affecting the guide-to-passenger-strand ratio of the miRNA let-7a. A multi-layered mechanism for the observed impact of Ago3 on the let-7a-3p passenger strand expression and activity is proposed. |
23748378 | The Ago3 PIWI domain is slicing competent but our Ago3 model suggests multiple interactions between residues in the PIWI & N domains that may increase protein rigidity or invoke other properties that contribute to Ago3's observed slicing deficiency. |
