Molecular Switch Engineering for Precise Genome Editing

Area of Science:

• Molecular Biology
• Genetics
• Biotechnology

Background:

• The discovery of zinc-finger nucleases in 1996 marked the beginning of genome editing technology.
• Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) associated protein 9 (Cas9) technology has made genome editing more accessible and cost-effective for mammalian cell research.
• A significant challenge in current genome editing is the occurrence of off-target effects, leading to unintended mutations in non-target DNA sequences.

Purpose of the Study:

• To review recent advancements in molecular and protein engineering aimed at enhancing the precision of genome editing tools.
• To explore the development of novel
• switching
• systems designed to control genome editing functions.

Main Methods:

• Focuses on molecular and protein engineering strategies.
• Discusses the design principles of novel
• switching
• mechanisms for genome editing tools.
• Reviews recent research efforts in developing precise genome editing systems.

Main Results:

• Molecular/protein engineering has led to significant improvements in genome editing technology.
• The development of
• switch
• -controlled systems is key to achieving precise editing.
• Novel switching systems are being designed to mitigate off-target effects.

Conclusions:
