Function

Required for RNA-mediated gene silencing (RNAi) by the RNA-induced silencing complex (RISC). The 'minimal RISC' appears to include AGO2 bound to a short guide RNA such as a microRNA (miRNA) or short interfering RNA (siRNA). These guide RNAs direct RISC to complementary mRNAs that are targets for RISC-mediated gene silencing. The precise mechanism of gene silencing depends on the degree of complementarity between the miRNA or siRNA and its target. Binding of RISC to a perfectly complementary mRNA generally results in silencing due to endonucleolytic cleavage of the mRNA specifically by AGO2. Binding of RISC to a partially complementary mRNA results in silencing through inhibition of translation, and this is independent of endonuclease activity. May inhibit translation initiation by binding to the 7-methylguanosine cap, thereby preventing the recruitment of the translation initiation factor eIF4-E. May also inhibit translation initiation via interaction with EIF6, which itself binds to the 60S ribosomal subunit and prevents its association with the 40S ribosomal subunit. The inhibition of translational initiation leads to the accumulation of the affected mRNA in cytoplasmic processing bodies (P-bodies), where mRNA degradation may subsequently occur. In some cases RISC-mediated translational repression is also observed for miRNAs that perfectly match the 3' untranslated region (3'-UTR). Can also up-regulate the translation of specific mRNAs under certain growth conditions. Binds to the AU element of the 3'-UTR of the TNF (TNF-alpha) mRNA and up-regulates translation under conditions of serum starvation. Also required for transcriptional gene silencing (TGS), in which short RNAs known as antigene RNAs or agRNAs direct the transcriptional repression of complementary promoter regions. (Microbial infection) Upon Sars-CoV-2 infection, associates with viral miRNA-like small RNA, CoV2-miR-O7a, and may repress mRNAs, such as BATF2, to evade the IFN response.

Activity summary

Argonaute-2 often referred to as Ago2 or Argonaute-2 protein plays an important role in the RNA-induced silencing complex (RISC). It has a molecular weight of approximately 97 kDa. Ago2 is found in the cytoplasm and nucleus of cells and is expressed in a wide range of tissues including the brain and liver. Its mechanical function involves binding to guide RNA and facilitating strand cleavage which is essential for gene silencing and regulation at the post-transcriptional level.

Biological function summary

The Argonaute-2 protein participates in gene silencing mechanisms. As a part of RISC Ago2 binds to microRNAs (miRNAs) or small interfering RNAs (siRNAs) to direct sequence-specific cleavage of target mRNAs regulating their translation and stability. This protein is a part of a multi-protein complex that modulates gene expression and influences cellular homeostasis and development. In its biological role Argonaute-2 impacts cellular differentiation proliferation and apoptosis.

Pathways

Several cellular processes require Argonaute-2 notably the RNA interference (RNAi) and microRNA (miRNA) pathways. In these pathways it interacts with Dicer a protein essential for the maturation of small RNA molecules and facilitates the gene silencing process. Ago2 is also involved in the regulation of gene expression during embryonic development and stress responses indicating its importance in maintaining cellular function and responding to environmental changes.

Associated diseases and disorders

Anomalies in Argonaute-2 activity correlate with cancer including lung and breast cancer where dysregulation of miRNA pathways can lead to unchecked cellular proliferation. It is also linked to neurological disorders like schizophrenia possibly due to its role in gene expression regulation in neural cells. Interactions between Ago2 and proteins like Dicer and other Argonautes suggest complex regulatory networks that when disrupted contribute to these diseases.
