A significant and global decrease in viral gene expression occurs with deletion of the carboxyl terminal domain of the human cytomegalovirus essential protein pUL34

ABSTRACT: The human cytomegalovirus UL34 gene encodes sequence-specific DNA-binding proteins and is essential for viral replication. Functionally, UL34 proteins (pUL34) repress expression of the viral immune evasion genes, US3 and US9. The amino terminal domain of pUL34 is sufficient for nuclear localization, DNA-binding and transcriptional repression. A virus lacking the entire carboxyl terminal of pUL34 was replication competent; however, deletion of the carboxyl terminal domain significantly impaired viral replication. There was a significant decrease in the transcription of viral genes at 4 hours post-infection following infection with the mutant virus which lacks the entire carboxyl terminal end of UL34 (UL34-COOH) relative to wild type virus, and an associated decrease in protein expression levels. Viral gene expression for the mutant virus was also decreased at 48 hpi but to a much smaller degree.

CDK12 globally stimulates RNA polymerase II transcription elongation and carboxyl-terminal domain phosphorylation

Project description:Cyclin-dependent kinase 12 (CDK12) phosphorylates the carboxyl-terminal domain (CTD) of RNA polymerase II (pol II) but its roles in transcription beyond the expression of DNA damage response genes remain unclear. Here, we have used TT-seq and mNET-seq to monitor the direct effects of rapid CDK12 inhibition on transcription activity and CTD phosphorylation in human cells. CDK12 inhibition causes a genome-wide defect in transcription elongation and a global reduction of CTD Ser2 and Ser5 phosphorylation. The elongation defect is explained by the loss of the elongation factors LEO1 and CDC73, part of PAF1 complex, and SPT6 from the newly-elongating pol II. Our results indicate that CDK12 is a general activator of pol II transcription elongation and indicate that it targets both Ser2 and Ser5 residues of the pol II CTD.

Mapping the anti-cancer activity of α-connexin carboxyl-terminal (aCT1) peptide in resistant HER2+ breast cancer

Project description: This study aims to examine the mechanisms for the anti-cancer effects of a therapeutic peptide agent targeted to connexin 43 (Cx43) called alpha-connexin carboxyl-terminal peptide (aCT1). Findings from this study identify the effect of aCT1 on breast cancer signaling using a resistant HER2+ breast cancer cell line.

The archaeal ATPase PINA interacts with the helicase Hjm via its carboxyl terminal KH domain remodeling and processing replication fork and Holliday junction

Project description:PINA is a novel ATPase and DNA helicase highly conserved in archaea, the third domain of life. The PINA from Sulfolobus islandicus (SisPINA) forms a hexameric ring, promotes Holliday junction (HJ) migration, and physically and functionally interacts with Hjc, the HJ specific endonuclease. Here, we show that SisPINA has strong physical interaction with Hjm (Hel308a), a helicase presumably targeting replication forks. In vitro biochemical analysis revealed that Hjm, Hjc, and SisPINA are able to coordinate HJ migration and cleavage in a concerted way. Deletion of the carboxyl 13 amino acid residues abolishes the interaction between SisPINA and Hjm. Crystal structure analysis showed that the carboxyl 70 amino acid residues fold into a type II KH domain which, in other proteins, functions in binding RNA and ssDNA. The KH domain not only mediates the interactions of PINA with Hjm and Hjc but also regulates the hexameric assembly of PINA. Our results collectively suggest possible mechanisms for SisPINA, Hjm, and Hjc to work together in replication fork regression, HJ formation, and HJ cleavage.

Transcriptomic analysis of third instar larva wing imaginal discs deregulating Cyclin G in Drosophila melanogaster

Project description:We report here the transcriptomic analysis of Drosophila melanogaster wing imaginal discs from third instar female larvae expressing Cyclin G deleted of the PEST domain (the 25 COOH-terminal amin-acids) under the control of the daugterless-Gal4 ubiquitous driver. The negative control was transgenic flies wearing only the daugterless-Gal4 driver.

Reduced Nucleoprotein availability impairs negative-sense RNA virus replication and promotes host recognition

Project description:Negative-sense RNA viruses (NSVs) rely on prepackaged viral RNA-dependent RNA polymerases (RdRp) to replicate and transcribe their viral genomes. Their replication machinery consists of an RdRp bound to viral RNA which is wound around a nucleoprotein (NP) scaffold, forming a viral ribonucleoprotein complex. NSV NP is known to regulate transcription and replication of genomic RNA, however its role in maintaining and protecting the viral genetic material is unknown. Here, we exploited host microRNA expression to target NP of influenza A virus and Sendai virus to ascertain how this would impact genomic levels and the host response to infection. We find that in addition to inducing a drastic decrease in genome replication, the antiviral host response in the absence of NP is dramatically enhanced. Additionally, our data shows that insufficient levels of NP prevent the replication machinery of these NSVs to process full-length genomes, resulting in aberrant replication products which form pathogen-associated molecular patterns in the process. These dynamics facilitate immune recognition by cellular pattern recognition receptors leading to a strong host antiviral response. Moreover, we observe that the consequences of limiting NP levels are universal amongst NSVs including Ebola virus, Lassa virus and Measles virus. Overall, these results provide new insights into viral genome replication of negative-sense RNA viruses and highlight novel avenues towards developing effective antiviral strategies, adjuvants, and/or live-attenuated vaccines.
