The style component of the self-incompatibility (S) locus of the wild tomato Lycopersicon peruvianum (L.) Mill. is an allelic series of glycoproteins with ribonuclease activity (S-RNases). Treatment of the S,-RNase from L . peruvianum with iodoacetate at p H 6.1 led to a loss of RNase activity. In the presence of a competitive inhibitor, guanosine 3”Ionophosphate (3‘-CMP), the rate of RNase ina...
ADAR1 isoforms are adenosine deaminases that edit and destabilize double-stranded RNA reducing its immunostimulatory activities. Mutation of ADAR1 leads to a severe neurodevelopmental and inflammatory disease of children, Aicardi-Goutiéres syndrome. In mice, Adar1 mutations are embryonic lethal but are rescued by mutation of the Mda5 or Mavs genes, which function in IFN induction. However, the ...
The regulation of ppp(A2'p)nA-(2-5A)-dependent RNase (RNase L or RNase F) was investigated in NIH 3T3, clone 1 cells using 2-5A-binding and nuclease activity assays. Minimal levels of 2-5A-dependent RNase were detected in actively dividing clone 1 cells; these levels were independently induced by growth arrest or interferon treatment. Accordingly, levels of the RNase were enhanced during growth...
The vaccinia virus E3L gene encodes two double-stranded RNA binding proteins that promote viral growth and pathogenesis through suppression of innate immunity. To explore how E3L enables vaccinia virus to evade the interferon system, cells and mice deficient in the principal interferon-regulated antiviral enzymes, PKR and RNase L, were infected with wild-type vaccinia virus and strains of vacci...
OBJECTIVE This study aims to explore the clinical characteristics of ABCE1 in esophageal cancers and its roles in the proliferation, invasiveness, migration and apoptosis of the esophageal carcinoma Eca109 cell line. METHODS The expression of ABCE1 and its target protein-RNase L, were first studied in tumor tissues of esophageal carcinoma and adjacent non-tumor tissues. The siRNA green fluore...
