Post-transcriptional gene silencing mediated by microRNAs is controlled by nucleoplasmic Sfpq [PDF]
Nature Communications, 2017 There is a growing body of evidence about the presence and the activity of the miRISC in the nucleus of mammalian cells. Here, we show by quantitative proteomic analysis that Ago2 interacts with the nucleoplasmic protein Sfpq in an RNA-dependent fashion.

The divergent V2 protein encoded by parsley yellow leaf curl virus is a suppressor of transcriptional and post-transcriptional gene silencing and a potential symptom determinant [PDF]
BMC Plant BiologyThe Geminiviridae family encompasses over 500 species of economically important plant viruses. A new geminivirus species named parsley yellow leaf curl virus (PYLCV) was first identified in 2020 in Southeastern Iran.

Beet Curly Top Iran Virus Rep and V2 Suppress Post-Transcriptional Gene Silencing via Distinct Modes of Action [PDF]
Viruses, 2023 Beet curly top Iran virus (BCTIV) is a yield-limiting geminivirus belonging to the becurtovirus genus. The genome organization of BCTIV is unique such that the complementary strand of BCTIV resembles Mastrevirus, whereas the virion strand organization is

MicroRNA chemical modifications in post-transcriptional gene silencing and human diseases [PDF]
Molecular Therapy: Nucleic AcidsMicroRNAs (miRNAs) are small, non-coding RNAs that influence various cellular activities through post-transcriptional gene silencing. Recent research has shown that miRNA modifications, including N6-methyladenosine (m6A), 5-methylcytidine (m5C), 2′-O ...

Cotton Leaf Curl Multan virus C4 protein suppresses both transcriptional and post-transcriptional gene silencing by interacting with SAM synthetase. [PDF]
PLoS Pathogens, 2018 Gene silencing is a natural antiviral defense mechanism in plants. For effective infection, plant viruses encode viral silencing suppressors to counter this plant antiviral response.

Comprehensive Mechanism of Gene Silencing and Its Role in Plant Growth and Development
Frontiers in Plant Science, 2021 Gene silencing is a negative feedback mechanism that regulates gene expression to define cell fate and also regulates metabolism and gene expression throughout the life of an organism.

Bidirectional transcription directs both transcriptional gene activation and suppression in human cells. [PDF]
PLoS Genetics, 2008 Small RNAs targeted to gene promoters in human cells have been shown to modulate both transcriptional gene suppression and activation. However, the mechanism involved in transcriptional activation has remained poorly defined, and an endogenous RNA ...

Post-transcriptional regulation of several biological processes involved in latex production in Hevea brasiliensis [PDF]
PeerJ, 2020 Background Small RNAs modulate plant gene expression at both the transcriptional and post-transcriptional level, mostly through the induction of either targeted DNA methylation or transcript cleavage, respectively.
