CONSTRUCTS AND METHODS FOR PREPARING CIRCULAR RNA

The present application provides linear RNA precursors and constructs for preparing circular RNAs (circRNAs) comprising an effector RNA sequence, such as a coding RNA sequence. In some embodiments, the linear RNA comprises from the 5′ end to the 3′ end: (a) a first portion of an RNA element (e.g., a...

More Information
Summary:The present application provides linear RNA precursors and constructs for preparing circular RNAs (circRNAs) comprising an effector RNA sequence, such as a coding RNA sequence. In some embodiments, the linear RNA comprises from the 5′ end to the 3′ end: (a) a first portion of an RNA element (e.g., an IRES), (b) an effector RNA sequence, and (c) a second portion of the RNA element, wherein the first and the second portions of the RNA element associate with each other to form a double-stranded region of at least 4 basepairs long, wherein the 5′ end of the first portion of the RNA element and the 3′ end of the second portion of the RNA element form a nick in the double-stranded region, and wherein an RNA ligase can ligate the nick. Also provided are methods of preparing circRNAs, circRNAs prepared thereof, and methods of using the circRNAs.
