Gene duplication of SNAPC1 generates transcription factors for snRNAs and sex-specific piRNAs

Piwi-interacting RNAs (piRNAs) are small non-coding RNAs essential for transposon silencing and germline integrity across metazoans. In many species, piRNA expression is sexually dimorphic, yet the molecular mechanisms underlying this sex specificity remain poorly understood. In Caenorhabditis elegans, sexually dimorph...

Dual-Binding Scaffold RRsS1 Bridges Pol IV Transcripts and DNA Templates for Robust Reproductive siRNA Biogenesis

J-domain proteins bridge the PKL and ATRX complex to transcription factors to fine-tune gene expression via H3.3 deposition

It is found that transcriptional outcome of PKL binding depends not only on the changes in H3.3 occupancy but also on the pre-existing chromatin context at PKL-targeted sites, which outlines a new mechanism for CHD3 chromatin remodeler recruitment and function.

Chromatin-Assisted Targeting Enables Precise DNA Methylation Editing in Plants

SunTag-NOVA robustly installed DNA methylation and repressed transcription at the endogenous FWA, FT and TMM genes with minimal genome-wide off-target consequences, and establishes SunTag-NOVA as a specific epigenome-editing platform for plants.
