  1. Tishkoff D, Johnson A, Kolodner R. Molecular and genetic analysis of the gene encoding the Saccharomyces cerevisiae strand exchange protein Sep1. Mol Cell Biol. 1991;11:2593-608 pubmed
    ..The interaction between sep1, rad50, and spo13 mutations suggested that SEP1 acts in meiosis in a pathway that is parallel to the RAD50 pathway. ..
  2. Johnson A, Kolodner R. Synthetic lethality of sep1 (xrn1) ski2 and sep1 (xrn1) ski3 mutants of Saccharomyces cerevisiae is independent of killer virus and suggests a general role for these genes in translation control. Mol Cell Biol. 1995;15:2719-27 pubmed
    ..Using a temperature-sensitive allele of SEP1/XRN1, we show that double mutants display a synthetic cell cycle arrest in late G1 at Start. ..
  3. Kim M, Krogan N, Vasiljeva L, Rando O, Nedea E, Greenblatt J, et al. The yeast Rat1 exonuclease promotes transcription termination by RNA polymerase II. Nature. 2004;432:517-22 pubmed
    ..These findings support a model in which poly(A) site cleavage and subsequent degradation of the 3'-downstream RNA by Rat1 trigger transcription termination. ..
  4. Wu C, Biernacki M, Kutok J, Rogers S, Chen L, Yang X, et al. Graft-versus-leukemia target antigens in chronic myelogenous leukemia are expressed on myeloid progenitor cells. Clin Cancer Res. 2005;11:4504-11 pubmed
    ..The present studies characterize expression of CML28 and CML66 in primary hematopoietic tissues...
  5. Vasiljeva L, Buratowski S. Nrd1 interacts with the nuclear exosome for 3' processing of RNA polymerase II transcripts. Mol Cell. 2006;21:239-48 pubmed
    ..Since Nrd1 is known to bind RNA polymerase II and be important for sn/snoRNA 3' end processing, Nrd1 may link transcription and RNA 3' end formation with surveillance by the exosome. ..
  6. Gabel H, Ruvkun G. The exonuclease ERI-1 has a conserved dual role in 5.8S rRNA processing and RNAi. Nat Struct Mol Biol. 2008;15:531-3 pubmed publisher
    ..8S ribosomal RNA in both C. elegans and S. pombe. In C. elegans, two protein isoforms of ERI-1 are localized to the cytoplasm, and each has distinct functions in ribosomal RNA processing and negative regulation of RNA interference. ..
  7. Tishkoff D, Rockmill B, Roeder G, Kolodner R. The sep1 mutant of Saccharomyces cerevisiae arrests in pachytene and is deficient in meiotic recombination. Genetics. 1995;139:495-509 pubmed
    ..We hypothesize that the Sep1 protein participates directly in meiotic recombination and that other strand exchange enzymes, acting in parallel recombination pathways, are able to substitute partially for the absence of the Sep1 protein. ..
  8. Yang X, Wu C, Chen L, Alyea E, Canning C, Kantoff P, et al. CML28 is a broadly immunogenic antigen, which is overexpressed in tumor cells. Cancer Res. 2002;62:5517-5522 pubmed
    ..Moreover, given its expression and immunogenicity in a wide variety of malignancies, CML28 merits additional evaluation as a target for antigen-specific immunotherapy. ..
  9. Kennedy S, Wang D, Ruvkun G. A conserved siRNA-degrading RNase negatively regulates RNA interference in C. elegans. Nature. 2004;427:645-9 pubmed
    ..Thus, ERI-1 is a negative regulator that may normally function to limit the duration, cell-type specificity or endogenous functions of RNA interference. ..

  1. Hieronymus H, Yu M, Silver P. Genome-wide mRNA surveillance is coupled to mRNA export. Genes Dev. 2004;18:2652-62 pubmed
    ..These results demonstrate coupling of mRNA surveillance to mRNA export and suggest specificity of the RNA surveillance machinery for different transcript populations. Broadly, these findings link DNA and RNA surveillance to mRNA export. ..
  2. Pearson E, Moore C. Dismantling promoter-driven RNA polymerase II transcription complexes in vitro by the termination factor Rat1. J Biol Chem. 2013;288:19750-9 pubmed publisher
    ..Upon this arrival, however, it is perhaps the specific and direct contact between Rat1 and Pol II that transmits the signal to terminate transcription. ..
