WO2013188037A2

A method of processing a target RNA comprising contacting the products of an RNA ligase–mediated ligation reaction with a CRISPR-associated (Cas)6 protein, where the RNA ligase–mediated ligation reaction comprises a target RNA, an RNA ligase, and first and second adaptors that can ligate with each other to produce an adaptor dimer that contains a CRISPR stem loop; the Cas6 protein recognizes the CRISPR stem loop, thus preventing the adaptor dimer from being reverse transcribed.

US8546553B2

A method of inactivating a target polynucleotide in a microbe comprising introducing into the microbe a plasmid DNA expressing small interfering RNA (psiRNA) comprising a 5´ region and a 3´ region, where the 5´ region is a psiRNA-tag of between 5 and 10 nucleotides chosen from a repeat from a CRISPR locus immediately upstream of a spacer, where the 3´ region comprises 18–75 nucleotides, and where the 3´ region is substantially complementary to a portion of the target polynucleotide, where the target polynucleotide is inactivated.

US20110217739A1

A polynucleotide comprising: a nucleotide sequence (a1) encoding a polypeptide having Cas6 endoribonuclease activity, where the amino acid sequence of the polypeptide has at least 80% sequence identity to a defined amino acid sequence, or the full complement of (a1); and a heterologous polynucleotide.

US20100076057A1

A method of inhibiting the function and/or presence of a target DNA sequence in a eukaryotic cell, comprising administering CRISPR RNA (crRNA) and one or more CRISPR-Cas proteins, or nucleic acid sequences encoding the Cas proteins, to a eukaryotic cell comprising a target DNA sequence, where the crRNA hybridizes with the target DNA sequence, thus interfering with the function and/or presence of the target DNA sequence.
