Abstract
The present disclosure provides compositions and methods for binding and/or cleaving a single stranded target nucleic acid. Subject compositions include a Cas9 polypeptide, a guide nucleic acid, and a PAMmer. A subject PAMmer is a single stranded oligonucleotide having a protospacer adjacent motif (PAM) sequence and at least one of: a specifity segment positioned 5' of the PAM sequence, and an orientation segment positioned 3′ of the PAM sequence. In some embodiments, the Cas9 polypeptide is a variant Cas9 polypeptide having reduced nuclease activity relative to a corresponding wild type Cas9 polypeptide. In some cases, methods of binding are for visualizing single stranded target nucleic acids using a detectable label. In some cases, methods of binding are for isolating, collecting, and/or analyzing at least one of: (i) bound single stranded target nucleic acids; and (ii) polypeptides associated with bound single stranded target nucleic acids.
