Etymology

Acronym of prime editing guide RNA.

Noun

pegRNA (countable and uncountable, plural pegRNAs)

  1. (genetics, molecular biology) A specialized guide RNA used in prime editing, comprising a single guide RNA (sgRNA) extended with a primer binding site (PBS) and a reverse transcription template (RTT) that encodes the desired genetic edit.

      Prime editors (PEs), initially represented by PE1, employed a reverse transcriptase (RT) fused to an RNA-programmable nickase (Cas9n) and a prime editing guide RNA (pegRNA) to directly copy genetic information from the extension on the pegRNA into the target genomic locus.
    • 2022, Marcello Maresca, Sumit Deswal, editors, Genome Editing in Drug Discovery, John Wiley & Sons, page 332:
      Briefly, upon Cas9-mediated nicking of the target site, the extended tail of the pegRNA hybridizes with the free 3' end, which serves as an RT template and encodes the desired edit to be incorporated into the genome.

      Upon expression of this prime editing construct, a complex of PE and pegRNA scans the DNA for the target site.
