RNA-guided transcriptional regulation
First Claim
1. A method of modulating expression of a target nucleic acid in a eukaryotic cell comprisingproviding to the cell a nucleic acid encoding a guide RNA complementary to the target nucleic acid sequence and an aptamer comprising a target of an RNA binding domain, wherein the aptamer is attached to the 3′
- end or the 5′
end of the guide RNA, wherein the guide RNA is a tracrRNA-crRNA fusion,providing to the cell a nucleic acid encoding a transcriptional activator or repressor and an RNA binding domain, wherein the RNA binding domain binds to the target of the RNA binding domain,providing to the cell a nucleic acid encoding a nuclease null Cas9 protein that interacts with the guide RNA, andwherein the cell expresses the guide RNA having the aptamer attached to the 3′
end or the 5′
end of the guide RNA, the transcriptional activator or repressor having the RNA binding domain and the Cas9 protein, andwherein the guide RNA including the transcriptional activator or repressor connected thereto and the Cas9 protein co-localize to the target nucleic acid sequence and wherein the transcriptional activator or repressor modulates expression of the target nucleic acid.

Abstract
Methods of modulating expression of a target nucleic acid in a cell are provided including introducing into the cell a first foreign nucleic acid encoding one or more RNAs complementary to DNA, wherein the DNA includes the target nucleic acid, introducing into the cell a second foreign nucleic acid encoding a nuclease-null Cas9 protein that binds to the DNA and is guided by the one or more RNAs, introducing into the cell a third foreign nucleic acid encoding a transcriptional regulator protein or domain, wherein the one or more RNAs, the nuclease-null Cas9 protein, and the transcriptional regulator protein or domain are expressed, wherein the one or more RNAs, the nuclease-null Cas9 protein and the transcriptional regulator protein or domain co-localize to the DNA and wherein the transcriptional regulator protein or domain regulates expression of the target nucleic acid.
