Within the nucleus, Dbp5p supports tRNA export providing a parallel mechanism by which this conserved DEAD-box protein functions to support eukaryotic gene expression.
Analysis of an essential motif in Mcm4 provides insights into replicative helicase double-hexamer formation and the first step requiring this intermediate during replication initiation.
Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.
A member of the Drosophila Nuclear Export Factor (Nxf) family, Nxf2, forms part of the piRNA-dependent co-transcriptional silencing complex and is essential for transposon repression in fly ovaries.
Interaction with PUMILIO is essential for maintenance of genomic stability by the cytoplasmic long noncoding RNA NORAD, whereas binding to RBMX is dispensable for this function.
Simultaneous targeting of loci by pathways that promote euchromatin and heterochromatin primes transcribed genes for epimutations in the form of CG DNA methylation.
Acetylation of the circadian transcription factor BMAL1 by the acetyltransferase TIP60 is crucial for recruitment of the pause release factors to clock gene promoters and productive elongation of these genes.
Multiple enhancers in physical proximity can reinforce shared transcriptional 'hubs' to preserve their transcriptional output, providing a buffer during environmental stresses and genetic perturbations to preserve phenotypic robustness.
RNAs enriched at cell protrusions are translated regardless of their location in the cytoplasm but are dynamically repressed in retracting protrusions and incorporated into heterogeneous RNA clusters.
Live-cell imaging shows that the contractile acto-myosin network on the nuclear envelope remnant positions chromosomes in early mitosis to ensure efficient and correct interactions between chromosomes and the mitotic spindle.
