Control of guanine-rich DNA secondary structures depending on the protease activity using a designed PNA peptide

We constructed a regulation system for DNA secondary structure formation of G-rich sequences using a designed PNA peptide exhibiting an on-to-off switching functionality, depending on the protease activity. This study introduces the new concept of a simple and powerful system for regulating quadrupl...

Description
Summary:We constructed a regulation system for DNA secondary structure formation of G-rich sequences using a designed PNA peptide exhibiting an on-to-off switching functionality, depending on the protease activity. This study introduces the new concept of a simple and powerful system for regulating quadruplex-related important biological events.
