HeLa nuclear extracts and RNase A were incubated with GST-PHAX and FLAG-UAP56 in the presence of ATP. The mixture was subjected to immunoprecipitation. The bound proteins were eluted with FLAG peptide. The eluate was subjected to GST pull-down. The bound proteins were treated with HRV 3C protease. S...

Dosage compensation in Drosophila is an epigenetic phenomenon utilizing proteins and long non-coding RNAs (lncRNAs) for transcriptional up-regulation of the entire X-chromosome. Here, UV cross-linking followed by deep sequencing (iCLIP) show that two enzymes in the Male-Specific Lethal complex, MLE ...

During ribosome biogenesis a plethora of assembly factors and essential enzymes drive the unidirectional maturation of nascent pre-ribosomal subunits. The DEAD-box RNA helicase Dbp10 is suggested to restructure pre-ribosomal rRNA of the evolving peptidyl-transferase center (PTC) on nucleolar ribosom...

Specific environmental insults cause the limited fragmentation of transfer RNAs (tRNAs) into tRNA-derived small RNAs (tsRNAs), which have been implicated in a wide range of biological processes. tRNA fragmentation results from endonucleolytic activities targeting single-stranded tRNA regions. Howeve...

DNA methylation in Arabidopsis thaliana is maintained by at least four different enzymes: MET1, CMT3, DRM2, and CMT2. However, DNA methylation is established exclusively by the enzyme DRM2, which acts in the RNA-directed DNA methylation (RdDM) pathway. Some RdDM components belong to gene families an...
