How Prime Editing Works
Prime Editing is a cutting-edge genetic engineering technology enabling accurate DNA modifications. It surpasses traditional CRISPR methods through its precision and adaptability.
Mechanism of Action
Prime Editing introduces the desired genetic change directly into the genome without creating double-strand breaks. The process uses a prime editor protein fused to a reverse transcriptase enzyme, guided by a pegRNA (prime editing guide RNA). This RNA contains a primer binding site, a reverse transcriptase template, and a guide sequence.
The pegRNA directs the prime editor to the target DNA sequence. The reverse transcriptase template within the pegRNA then synthesizes the new DNA strand to integrate the intended edit seamlessly.
Key Components
Prime Editor Protein: This enzyme combines a Cas9 nickase with a reverse transcriptase. It introduces a nick to the DNA strand, then uses the nicked strand as a primer for synthesis, allowing edits to be precisely incorporated.
pegRNA (Prime Editing Guide RNA): This RNA guides the prime editor to the specific DNA site for editing. It contains three main parts: a protospacer that locates the target sequence, a primer binding site that initiates synthesis, and a template that provides the new genetic information.
Reverse Transcriptase: This enzyme synthesizes DNA from an RNA template. Within Prime Editing, it's fused to the Cas9 nickase, enabling direct insertion of the desired genetic change into the target DNA.
Prime Editing holds profound potential, not just in correcting genetic disorders but also in advancing areas like anti-aging supplements. Innovations using Prime Editing could complement new supplements such as NMN and resveratrol, enhancing our understanding of healthy aging.
