26728557 P-TEFb regulates termination by promoting chromatin recruitment and activation of a cotranscriptional RNA processing enzyme, Xrn2.
26531822 The results suggest that CARF regulates early steps of pre-rRNA processing during ribosome biogenesis by controlling spatial distribution of XRN2 between the nucleoplasm and nucleolus.
26474067 Kinetic competition between elongating pol II and the Xrn2 exonuclease is integral to termination of transcription on most human genes.
26340924 Chromatin immunoprecipitation experiments further show that IL-1 stimulation leads to decrease in NKRF aa 421-429 phosphorylation and dissociation of NELF-E and XRN2 by concomitant resumption of transcription elongation of a synthetic reporter
26159921 found that the 3' fragments of target pre-mRNA generated by ASO were almost completely degraded from their 5' ends by nuclear XRN2 after RNase H1-mediated cleavage
25673723 The restriction of JFH1 and H77D hepatitis C virus replication by Xrn2 is likely indirect in nature and possibly linked to cytopathic effects of these robustly replicating viruses.
25128458 Mammalian target of rapamycin protein regulates the diffusion of Xrn2 from the nucleolus to the nucleoplasm under heat stress conditions.
25121753 Xrn2 has a cytoplasmic, antiviral function against HCV that is counteracted by HCV's subversion of miR-122 to form a protective oligomeric complex at the 5' end of the viral genome.
25010285 Interaction of HIV-1 Gag with 5'-3' exoribonuclease 2 (XRN2) is identified in a series of six affinity purification/mass spectrometry screens
23857582 hnRNPK may play a role in recruitment of XRN2 to gene loci thus regulating coupling 3'-end pre-mRNA processing to transcription termination.
22980978 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 cleavage of the stem-loop RNA, TAR.
22522706 Xrn2 associated with and co-transcriptionally degraded nascent beta-globin transcripts. Evidence was provided that many endogenous pre-mRNAs are also co-transcriptionally degraded by Xrn2 when their processing is inhibited by Spliceostatin A.
22483619 Xrn2 has a role in control of transcription by RNA polymerase II.
21700224 The results predict that senataxin is required for the resolution of R-loops formed downstream of the poly(A) signal, allowing Xrn2 recruitment and efficient Pol II transcriptional termination.
19915612 Genetic variants regulating Xrn2 expression in cis are determinants of spontaneous lung tumor susceptibility in mice and have genetic equivalents in lung cancer susceptibility in human beings.
18955505 Degradation of the downstream cleavage product (DCP) does not depend on the Xrn2 5' exonuclease, suggesting that CPSF-73 degrades the DCP both in vitro and in vivo.
17639083 p54 is present along the length of genes, and small interfering RNA (siRNA)-mediated knockdown leads to defects in XRN2 recruitment and termination.
16147866 XRN2b is mainly expressed in blood leukocyte tissue, while XRN2a is detected in several human tissues and in human tumor tissues
15565158 co-transcriptional cleavage acts as a precursor to termination by presenting a free RNA 5' end that is recognized by the human 5' --> 3' exonuclease Xrn2
