Abstract

The present disclosure provides modified nucleosides, nucleotides, and nucleic acids, and methods of using thereof.

Claims (1)

1. A messenger ribonucleic acid (mRNA) comprising a nucleotide that disrupts a binding of a major groove binding partner with the mRNA, wherein the nucleotide has decreased binding affinity to the major groove binding partner selected from the group consisting of toll-like receptor (TLR) 3, TLR7, TLR8, retinoic acid-inducible gene I (RIG-I), melanoma differentiation-associated gene 5 (MDA5) and laboratory of genetics and physiology 2 (LGP2), and wherein the nucleotide comprises a modification on the major groove face of the nucleobase where an atom of the major groove face of the nucleobase is replaced or substituted with a C 1 -C 6 alkyl group.
