    • Oligomeric compounds including oligoribonucleotides and oligoribonucleosides are provided that have subsequences of 2null-pentoribofuranosyl nucleosides that activate dsRNase. The oligoribonucleotides and oligoribonucleosides can include substituent groups for increasing binding affinity to complementary nucleic acid strand as well as substituent groups for increasing nuclease resistance. The oligomeric compounds are useful for diagnostics and other research purposes, for modulating the expression of a protein in organisms, and for the diagnosis, detection and treatment of other conditions susceptible to oligonucleotide therapeutics. Also included in the invention are mammalian ribonucleases, i.e., enzymes that degrade RNA, and substrates for such ribonucleases. Such a ribonuclease is referred to herein as a dsRNase, wherein nulldsnull indicates the RNase's specificity for certain double-stranded RNA substrates. The artificial substrates for the dsRNases described herein are useful in preparing affinity matrices for purifying mammalian ribonuclease as well as non-degradative RNA-binding proteins.
    • 提供了包含寡核糖核苷酸和寡核糖核苷的寡聚化合物,其具有激活dsRNase的2'-戊二呋呋糖基核苷的亚序列。 寡核糖核苷酸和寡核糖核苷可以包括用于增加对互补核酸链的结合亲和力的取代基以及用于增加核酸酶抗性的取代基。 寡聚化合物可用于诊断和其他研究目的,用于调节生物体中的蛋白质的表达,以及用于诊断,检测和治疗对寡核苷酸治疗剂敏感的其它病症。 本发明还包括哺乳动物核糖核酸酶,即降解RNA的酶和这种核糖核酸酶的底物。 这样的核糖核酸酶在本文中称为dsRNase,其中“ds”表示RNase对某些双链RNA底物的特异性。 本文所述的dsR酶的人造底物可用于制备用于纯化哺乳动物核糖核酸酶以及非降解性RNA结合蛋白的亲和基质。
