Authors use a series of assays to demonstrate that the 3'-terminal portion of the nucleocapsid (N) mRNA of Rift Valley fever virus can effectively stall and repress XRN1. The region responsible for impeding XRN1 includes a G-rich portion that likely forms a G-quadruplex structure. The 3'-terminal portions of ambisense-derived transcripts of multiple arenaviruses also stalled XRN1.
Insertion of 5'-3' exoribonuclease 1 (XRN1)-resistant sequences (xrRNAs) into different reporter mRNAs allowed to monitor RNA decay activity by the nonsense-mediated mRNA decay pathway (NMD).
These findings suggest that sequestration of the exoribonucleases DIS3L2 and XRN1 to nuclear inclusions may be related to the pathogenesis of intranuclear inclusion body disease
Data show that the AR-miR-204-XRN1-miR-34a positive feedback loop and a dual function of miR-204/XRN1 axis in prostate cancer.
Thus, Xrn1 is a cellular factor regulating dsRNA accumulation and dsRNA-responsive innate immune effectors.
Occupation of each miR-122 binding site on 5' untranslated region of the hepatitis C virus genome contributes equally and cooperatively to virus replication via protecting from Xrn1 exoribonuclease degradation.
Authors conclude that Xrn1 is the dominant 5' exoribonuclease mediating decay of hepatitis C virus RNA and that miR-122 provides protection against it
Mouse Xrn1 plays a role in RNA turnover.
Data show that 5' exonuclease Xrn1 knockdown and miR-122 supplementation have equal, redundant, and nonadditive effects on the rate of viral RNA decay, indicating that miR-122 protects HCV RNA from 5' decay.
findings reveal a role for XRN1 in decapping and provide a molecular basis for the coupling of decapping to 5'-->3' mRNA degrada
LSm1-7 proteins colocalize with DCP1,DCP2 and Xrn1 in cytoplasmic foci
SEP1 localizes to cytoplasmic foci containing a complex of mRNA-degrading enzymes. In addition to mRNA metabolism, yeast Sep1 has been implicated in a variety of nuclear and cytoplasmic functions, including homologous recombination, meiosis, telomere maintenance, and microtubule assembly.
