5'-3' exoribonuclease 2

This gene shares similarity with the mouse Dhm1 and the yeast dhp1 gene. The yeast gene is involved in homologous recombination and RNA metabolism, such as RNA synthesis and RNA trafficking. Complementation studies show that Dhm1 has a similar function in mouse as dhp1. The function of the human gene has not yet been determined. Transcript variants encoding different isoforms have been noted for this gene; however, their full-length nature is not known. [provided by RefSeq, Jul 2008] (from NCBI)

Papers on Xrn2
Collaborator of alternative reading frame protein (CARF) regulates early processing of pre-ribosomal RNA by retaining XRN2 (5'-3' exoribonuclease) in the nucleoplasm.
Takahashi et al., Tokyo, Japan. In Nucleic Acids Res, 03 Dec 2015
In this study, we demonstrate that CARF associates with 5'-3' exoribonuclease 2 (XRN2), which plays a major role in both the maturation of rRNA and the degradation of a variety of discarded pre-rRNA species.

The torpedo model of transcription termination asserts that the exonuclease Xrn2 attacks the 5'PO4-end exposed by nascent RNA cleavage and chases down the RNA polymerase.
NF-κB-repressing factor phosphorylation regulates transcription elongation via its interactions with 5'→3' exoribonuclease 2 and negative elongation factor.
Nourbakhsh et al., Hannover, Germany. In Faseb J, 04 Oct 2015
In copurification studies, aa 421-429 is required for interactions between NKRF, 5'→3' exoribonuclease 2 (XRN2) and the negative elongation factor (NELF)-E in HeLa cells.
XRN2 is required for the degradation of target RNAs by RNase H1-dependent antisense oligonucleotides.
Obika et al., Suita, Japan. In Biochem Biophys Res Commun, Sep 2015
To better understand this degradation pathway, we depleted the expression of two major 5' to 3' exoribonucleases (XRNs), named XRN1 and XRN2, and analyzed the levels of 3' fragments of the target RNAs in vitro.
Interaction of host cell microRNAs with the HCV RNA genome during infection of liver cells.
Sarnow et al., Stanford, United States. In Semin Liver Dis, Feb 2015
In this review, the authors summarize the molecular mechanism by which miR-122 protects the HCV RNA genome from degradation by exoribonucleases Xrn1 and Xrn2 and discuss the application of miR-122 antisense molecules in the clinic.

XRN2 is a 5'→3' exoribonuclease that is evolutionarily conserved in eukaryotes.
XRN 5'→3' exoribonucleases: structure, mechanisms and functions.
Green et al., Newark, United States. In Biochim Biophys Acta, 2013
Highly conserved across species, the family is typically represented by one cytoplasmic enzyme (XRN1/PACMAN or XRN4) and one or more nuclear enzymes (XRN2/RAT1 and XRN3).
Microprocessor, Setx, Xrn2, and Rrp6 co-operate to induce premature termination of transcription by RNAPII.
Kiernan et al., Montpellier, France. In Cell, 2012
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.
Co-transcriptional degradation of aberrant pre-mRNA by Xrn2.
West et al., Edinburgh, United Kingdom. In Embo J, 2012
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.

Gromak et al., Oxford, United Kingdom. In Mol Cell, 2011
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.

MicroRNAses and the regulated degradation of mature animal miRNAs.
Chatterjee et al., Basel, Switzerland. In Adv Exp Med Biol, 2009
Initially thought to be very stable with half-lives on the order of days, mature miRNAs have recently been shown to be subject to degradation by 'microRNases' (miRNases) in plants (the small RNA degrading nucleases, SDN) and animals (exoribonuclease 2/XRN-2/XRN2).
