In diffuse large B-cell lymphoma (DLBCL) poor outcome is associated with EIF4B-dependent stimulation of the DEAD box helicase eIF4A that unwinds RNA structures in 5’ untranslated regions (UTRs) in mRNAs that encode proteins with a role in cell proliferation. We carried out iCLIP to examine differenc...

We developed a customized RNA-Seq strategy to identify the 3' termini of degradation intermediates of histone mRNAs. Using this strategy, we identified two types of oligouridylated degradation intermediates: RNAs ending at different sites of the 3' side of the stemloop that resulted from initial deg...

The animal replication-dependent (RD) histone mRNAs are coordinately regulated with chromosome replication. They are the only known cellular mRNAs that are not polyadenylated. Instead, the mature transcripts end in at a conserved stem-loop (SL) structure. This SL structure interacts stably with the...

This study uses individual-nucleotide resolution UV crosslinking and immunoprecipitation (iCLIP) to map the direct RNA-binding sites of the PETISCO complex in Caenorhabditis elegans embryos. When bound to TOST-1, PETISCO stabilizes replication-dependent histone mRNAs during oogenesis to ensure adequ...

To identify components of the U7 snRNP, we used cleavage-resistant histone pre-mRNA containing biotin and a photo-sensitive linker and purify processing complexes from Drosophila and mouse nuclear extracts.
