WormBase Gene ID  ? WBGene00006964 Gene Name  xrn-2
Sequence Name  ? Y48B6A.3 Brief Description  xrn-2 encodes a 5'-3' exoribonuclease orthologous to Saccharomyces cerevisiae Rat1p; XRN-2 activity is required for degradation and hence regulation of levels of mature miRNAs such as let-7; accordingly, loss of xrn-2 activity affects miRNA-mediated processes such as molting, specifically shedding cuticle from the pharynx, and regulation of vulval development; an xrn-2::gfp promoter fusion is expressed in the pharyngeal myoepithelium, the intestine, and neurons.
Organism  Caenorhabditis elegans Automated Description  Enables 5'-3' RNA exonuclease activity. Involved in several processes, including miRNA catabolic process; negative regulation of miRNA-mediated gene silencing; and regulation of vulval development. Located in nucleus. Expressed in M5 neuron; PVT; intestine; and pharyngeal epithelial cell. Human ortholog(s) of this gene implicated in adenoid cystic carcinoma; leiomyosarcoma; and lung cancer. Is an ortholog of human XRN2 (5'-3' exoribonuclease 2).

adult vs dauer larva Transcripts that showed differential expression in adult vs dauer lava in N2 animals at 20C. N.A. WBPaper00050488:adult_vs_dauer_regulated_N2_20C
  mRNAs that showed decreased expression in 1 cell mebryo comparing to in oocyte, according to RNAseq analysis. Gaussian error propagation. As cutoff for the up-regulated genes authors used log2 fold change > 1 and P < 0.05 and as cutoff for the down-regulated genes authors used log2 fold change < -1 and P < 0.05. WBPaper00045420:fertilization_downregulated_transcript
  Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr reference). A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

    Expr3697 Fluorescence was observed in epithelial cells that synthesize cuticle. The gfp fusion gene for the exoribonuclease xrn-2 was expressed in specialized myoepithelial cells that secrete the pharyngeal cuticle. Expression of xrn-2p::gfp in the pharyngeal myoepithelium intensified prior to molting. xrn-2p::gfp was expressed in several anterior neurons, including sensory neurons, as well as the PVT neuron that projects along the ventral cord, and the M5 pharyngeal neuron. Also, xrn-2p::gfp was expressed in M5 only in larvae. The xrn-2 reporter was also expressed in the intestine. However, expression of xrn-2p::gfp in the intestine persisted in adults that no longer molt. Expression of the gfp fusion genes was never detected in the hypodermis of gravid adults that no longer molt.

    Expr11496 xrn-2 is expressed broadly, perhaps ubiquitously, across tissues and developmental stages. This expression was further validated through a time course that followed endogenous XRN2 protein by western blotting, and equally revealed continuous xrn-2 expression throughout the C. elegans life cycle.
