SETX sumoylation
Senataxin (SETX) is a putative RNA:DNA helicase that is mutated in two distinct juvenile neurological disorders, AOA2 and ALS4. SETX is involved in the response to oxidative stress and is suggested to resolve R loops formed at transcription termination sites or at sites of collisions between the transcription and replication machineries. R loops are hybrids between RNA and DNA that are believed...
متن کاملMicroprocessor, Setx, Xrn2, and Rrp6 Co-operate to Induce Premature Termination of Transcription by RNAPII
Transcription elongation is increasingly recognized as an important mechanism of gene regulation. Here, we show that microprocessor controls gene expression in an RNAi-independent manner. Microprocessor orchestrates the recruitment of termination factors Setx and Xrn2, and the 3'-5' exoribonuclease, Rrp6, to initiate RNAPII pausing and premature termination at the HIV-1 promoter through cleavag...
متن کاملAntiviral response dictated by choreographed cascade of transcription factors.
The dendritic cell (DC) is a master regulator of immune responses. Pathogenic viruses subvert normal immune function in DCs through the expression of immune antagonists. Understanding how these antagonists interact with the host immune system requires knowledge of the underlying genetic regulatory network that operates during an uninhibited antiviral response. To isolate and identify this netwo...
متن کاملSensitivity of Mitochondrial Transcription and Resistance of RNA Polymerase II Dependent Nuclear Transcription to Antiviral Ribonucleosides
Ribonucleoside analogues have potential utility as anti-viral, -parasitic, -bacterial and -cancer agents. However, their clinical applications have been limited by off target effects. Development of antiviral ribonucleosides for treatment of hepatitis C virus (HCV) infection has been hampered by appearance of toxicity during clinical trials that evaded detection during preclinical studies. It i...
متن کاملSmall carboxyl-terminal domain phosphatase 2 attenuates androgen-dependent transcription.
Small carboxyl-terminal domain (CTD) phosphatase 2 (SCP2) was identified and verified as a protein that interacts with the androgen receptor (AR). Ectopic expression of SCP2 or two other family members, SCP1 and SCP3, attenuated AR transcriptional activity in LNCaP cells and were recruited in an androgen- and AR-dependent fashion onto the prostate-specific antigen (PSA) promoter. Silencing SCP2...
