The landscape of RNA polymerase II transcription initiation in C. elegans reveals a novel regulatory architecture

Project description:It has recently been shown that RNA Polymerase II transcription is far more extensive than previously thought, much of it not associated with protein-coding genes. To investigate this phenomenon, we determined the genome-wide landscape of RNA Polymerase II transcription initiation and elongation in C. elegans. We identify 73,500 distinct clusters of transcription initiation and find that initiation is often bidirectional. Strikingly, the majority of initiation events occur in regions with enhancer-like chromatin signatures. We also assign transcription initiation sites to 7691 protein coding genes, the majority previously unknown because of trans-splicing. Through mapping RNA PolII initiation (short capped RNAs) and elongation (long capped RNAs), we provide identification of transcription start sites.

Caenorhabditis elegans mRBPome

Project description:This project aims to identify novel RNA binding proteins in the nematode, Caenorhabditis elegans. Since interactions between RNAs and proteins may be transient, these animals were crosslinked with UV light at 254 nm which promotes the covalent link between proteins and RNAs. After this, polyadenylated mRNAs were purified via oligo(dT) coupled to magentic beads under stringent conditions. Finally, samples were subjected to mass spectrometry analysis. To rule out the possibility of RNA-independent binding we also analysed other samples: i) samples digested with RNase one; ii) samples where we performed competition assays with polyadenylic acid

Mitochondrial mutant Caenorhabditis elegans phosphoproteome

Project description:Inhibition of insulin/IGF-1 signaling (IIS) represents a promising avenue for the treatment of mitochondrial diseases, although many of the molecular mechanisms underlying this beneficial effect remain elusive. Here, we investigate the phosphoproteomic landscape of Caenorhabditis elegans with severe mitochondrial deficiency in the context of insulin signaling inhibition.

CCAR-1 regulates the alternative splicing of multiple genes in Caenorhabditis elegans

Project description:The Cell Division Cycle and Apoptosis Regulator (CCAR) protein family members have recently emerged as regulators of alternative splicing and transcription, as well as having other key physiological functions. For example, mammalian CCAR2/DBC1 forms a complex with the zinc factor protein ZNF326 to integrate alternative splicing with RNA polymerase II transcriptional elongation in AT-rich regions of the DNA. Additionally, Caenorhabditis elegans CCAR-1, a homolog to mammalian CCAR2, facilitates the alternative splicing of the perlecan unc-52 gene. However, much about the CCAR family's role in alternative splicing is unknown. We are interested in uncovering the role of the CCAR family in alternative splicing in vivo using Caenorhabditis elegans. We examined the role of CCAR-1 in genome-wide alternative splicing and identified new alternative splicing targets of CCAR-1 using RNA sequencing. Also, we found that CCAR-1 interacts with the spliceosome factors UAF-1 and UAF-2 using mass spectrometry, and that knockdown of ccar-1 affects alternative splicing patterns, motility, and proteostasis of UAF-1 mutant worms. Collectively, we demonstrate a role for CCAR-1 in the regulation of global alternative splicing in C. elegans and in conjunction with UAF-1
