Stabilized external guide sequences

摘要

Modified external guide sequence (EGS) molecules that mediate cleavage of specific target RNAs have been constructed. The modified molecules are external guide sequence molecules for RNAse P which are designed to specifically bind to and promote RNAse P-mediated cleavage of target RNA molecules and to have enhanced nuclease resistance. Specific regions are modified to achieve enhanced stability while maintaining RNAse P activity. Modified external guide sequence molecules suitable for use in the treatment of hepatitis B viral infections have been constructed.
