The Varied Roles of Nuclear Argonaute-Small RNA Complexes and Avenues for Therapy

open access: yesMolecular Therapy: Nucleic Acids, 2014
Argonautes are highly conserved proteins found in almost all eukaryotes and some bacteria and archaea. In humans, there are eight argonaute proteins evenly distributed across two clades, the Ago clade (AGO1-4) and the Piwi clade (PIWIL1-4).

Argonaute 2 drives miR-145-5p-dependent gene expression program in breast cancer cells [PDF]

open access: yes, 2019
To perform their regulatory functions, microRNAs (miRNAs) must assemble with any of the four mammalian Argonaute (Ago) family of proteins, Ago1–4, into an effector complex known as the RNA-induced silencing complex (RISC).

Asymmetric expression of Argonautes in reproductive tissues [PDF]

open access: yesPlant Physiology, 2021
The Arabidopsis genome encodes ten Argonautes proteins showing distinct expression pattern as well as intracellular localisation during sexual reproduction.

Human GW182 Paralogs Are the Central Organizers for RNA-Mediated Control of Transcription

open access: yesCell Reports, 2017
In the cytoplasm, small RNAs can control mammalian translation by regulating the stability of mRNA. In the nucleus, small RNAs can also control transcription and splicing.

microRNA-mediated regulation of microRNA machinery controls cell fate decisions

open access: yeseLife, 2021
microRNAs associate with Argonaute proteins, forming the microRNA-induced silencing complex (miRISC), to repress target gene expression post-transcriptionally.

Nucleotide bias of DCL and AGO in plant anti-virus gene silencing [PDF]

open access: yes, 2010
Plant Dicer-like (DCL) and Argonaute (AGO) are the key enzymes involved in anti-virus post-transcriptional gene silencing (AV-PTGS). Here we show that AV-PTGS exhibited nucleotide preference by calculating a relative AV-PTGS efficiency on processing ...

A structural view of microRNA-target recognition [PDF]

open access: yes, 2016
It is well established that the correct identification of the messenger RNA targeted by a given microRNA (miRNA) is a difficult problem, and that available methods all suffer from low specificity.

Structural basis of antiphage immunity generated by a prokaryotic Argonaute-associated SPARSA system

open access: yesNature Communications
Short prokaryotic Argonaute and Sir2 proteins function as an antivirus system. Here the authors describe structures of SPARSA (a heterodimer of Sir2-APAZ and prokaryotic Argonaute) with and without template DNA and guide RNA, providing structural basis ...

Mammalian Argonaute-DNA binding? [PDF]

open access: yesBiology Direct, 2014
When a field shares the consensus that a particular phenomenon does NOT occur, this may reflect extensive experimental investigations with negative outcomes, or may represent the "common sense" position based on current knowledge and established ways of thinking.

HDAC1 SUMOylation promotes Argonaute-directed transcriptional silencing in C. elegans

open access: yeseLife, 2021
Eukaryotic cells use guided search to coordinately control dispersed genetic elements. Argonaute proteins and their small RNA cofactors engage nascent RNAs and chromatin-associated proteins to direct transcriptional silencing.
