The molecular determinants for neuronal subcellular RNA transport by FMRP are defined, with interactions between RNA G-quadruplexes and the RGG domain of FMRP being of critical importance.
The crystal structure of human Holliday junction resolvase GEN1 in complex with DNA reveals a conserved chromodomain as an additional DNA-anchoring point that opens new perspectives for enzyme regulation.
SeqZip is a new DNA ligation-based method to condense and maintain exon connectivity information within individual RNA molecules, which can provide new insights into alternative splicing.
Human genomic DNA contains uracil in the late replicating, constitutive heterochromatic regions, while treatment with drugs perturbing thymidylate biosynthesis shifts the uracil distribution pattern towards the euchromatin in UNG-inhibited cells.
Upon genotoxic stress, the FBXL10-RNF68-RNF2 ubiquitin ligase complex mono-ubiquitylates histone H2A and mediates H2A/H2A.Z exchange to repress transcription and ensures proper high fidelity homologous recombination repair.
Human proteins that add or remove the methyladenosine modification of cellular RNA, or recognize methylated RNA significantly affect HIV-1 infection or viral protein synthesis in cells, suggesting an important role for HIV-1 RNA methylation in regulating viral replication.
In nematode worms, NSUN-1 methylates ribosomal RNA and influences phenotypes related to aging, stress resistance, germ line development, and cuticle integrity by regulating translation of specific mRNAs.
The genome sequence of Trichoplusia ni enables the use of this widespread lepidopteran pest as a model for both the study of small RNA pathways and insecticide resistance.
The engagement of DNA crossings is shown to license ATP hydrolysis and DNA cleavage by topoisomerase VI, a finding with mechanistic ramifications for related GHKL ATPases and meiotic recombination machineries.
CUT&RUN (Cleavage Under Targets & Release Using Nuclease) profiles antibody-targeted DNA-binding proteins in situ with high resolution and low background, providing a simple, robust and scalable alternative to chromatin immunoprecipitation.
