Title: Oligoribonucleotides and Ribonucleases for Cleaving RNA
Patent Number: 7,629,321
Filed: Oct. 25, 2002
Inventor: Stanley Crooke, Isis Pharmaceuticals
The patent, its abstract states, claims "oligomeric compounds including oligoribonucleotides and oligoribonucleosides … [with] subsequences of 2'-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," the abstract adds. "Such a ribonuclease is referred to herein as a dsRNase, wherein 'ds' 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."
