Seeking the truth behind the myth: Argonaute tales from “nuclearland”
(Cell Press, 2022-02)
Argonaute proteins have been traditionally characterized as a highly evolutionary conserved family engaged in post-transcriptional gene silencing pathways. The Argonaute family is mainly grouped into the AGO and PIWI clades. ...
Argonaute proteins: Why are they so important for the legume–rhizobia symbiosis?
(Frontiers Media S.A., 2019-10)
Unlike most other land plants, legumes can fulfill their nitrogen needs through the establishment of symbioses with nitrogen-fixing soil bacteria (rhizobia). Through this symbiosis, fixed nitrogen is incorporated into the ...
Nuclear role for human Argonaute-1 as an estrogen-dependent transcription coactivator
(Rockefeller University Press, 2020-09)
In mammals, argonaute (AGO) proteins have been characterized for their roles in small RNA mediated posttranscriptional and also in transcriptional gene silencing. Here, we report a different role for AGO1 in estradiol-triggered ...
Alfalfa dwarf cytorhabdovirus P protein is a local and systemic RNA silencing supressor which inhibits programmed RISC activity and prevents transitive amplification of RNA silencing
(Elsevier Science, 2016-09)
Plants employ RNA silencing as an innate defense mechanism against viruses. As a counter-defense, plant viruses have evolved to express RNA silencing suppressor proteins (RSS), which target one or more steps of the silencing ...

Identificação e caracterização da argonauta TcPIWI e de pequenos RNAs em Trypanosoma cruzi
(Universidade Federal de Minas GeraisUFMG, 2015-09-22)
Trypanosoma cruzi is an intracellular parasite, etiological agent of Chagas disease, with a complex life cycle between two hosts and displays different life stages. In order to adapt to the different challenges that undergoes ...
Argentinian potato leafroll virus P0 protein: Novel activities for a previously known suppressor
(Wiley Blackwell Publishing, Inc, 2020-10-08)
The potato leafroll virus (PLRV) P0 protein (P0PL) is a suppressor of RNA silencing. In this study, we showed that P0 protein from an Argentinian isolate of PLRV (P0PL-Ar) has an additional activity not described for other ...
Argonaute-1 binds transcriptional enhancers and controls constitutive and alternative splicing in human cells
(National Academy Of Sciences, 2014-10)
The roles of Argonaute proteins in cytoplasmic microRNA and RNAi pathways are well established. However, their implication in small RNA-mediated transcriptional gene silencing in the mammalian cell nucleus is less understood. ...
Autoantibodies to argonaute 2 (su antigen)
(2013)
Like many other classical autoantibodies in systemic rheumatic diseases, anti-Su antibodies were originally defined by the double immunodiffusion assay in the early 80s. However, despite its high prevalence, only a few ...
