MetabolomicsA cytochrome P450 CYP87A4 imparts sterol side-chain cleavage in digoxin biosynthesis
Digoxin extracted from the foxglove plant is a widely prescribed natural product for treating heart failure. It is listed as an essential medicine by the World Health Organization. However, how the foxglove plant synthesizes digoxin is mostly unknown, especially the cytochrome P450 sterol side chain...

TranscriptomicsCleavage Factor Im as a key regulator of 3’ UTR length
In eukaryotes, the 3' ends of RNA polymerase II-generated transcripts are made in the majority of cases by site-specific endonucleolytic cleavage, followed by the addition of a poly(A) tail. By alternative polyadenylation, a gene can give rise to multiple mRNA isoforms that differ in the length of t...

TranscriptomicsGlobal analyses of endonucleolytic cleavage in mammals reveal expanded repertoires of cleavage-inducing small RNAs and their targets
In mammals, small RNAs are important players in post-transcriptional gene regulation. While their roles in mRNA destabilization and translational repression are well appreciated, their involvement in endonucleolytic cleavage of target RNAs is poorly understood. Very few microRNAs are known to guide ...

TranscriptomicsRibonuclease L and Metal-Ion-Independent Endoribonuclease Cleavage Sites in Host and Viral RNAs
We used 2', 3'-cyclic phosphate cDNA synthesis and Illumina sequencing to identify and quantify metal-ion-independent endoribonuclease cleavage sites in host and viral RNAs. To make cDNA libraries, we exploited the 2’, 3’-cyclic phosphate at the end of RNA fragments produced by RNase L and other met...

TranscriptomicsPaf1C plays novel subunit-specific roles in alternative cleavage and polyadenylation
The PAF complex (Paf1C) has been shown to regulate chromatin modifications, gene transcription, and PolII elongation. Here, we provide the first genome-wide analysis of chromatin occupancy by the entire PAF complex in mammalian cells. We show that Paf1C is recruited not only to promoters and gene bo...

TranscriptomicsDiverse endonucleolytic cleavage sites in the mammalian transcriptome depend upon microRNAs, Drosha, and additional nucleases
Messenger RNAs are regulated by a variety of degradation mechanisms in mammalian cells. In the canonical animal microRNA pathway, microRNAs in complex with Argonaute proteins bind to many mRNA targets with imperfect complementarity, leading to degradation of the mRNA through the regular decay machi...
