Background: Cpf1
Cpf1 represents a new generation of CRISPR effector nucleases first isolated from Prevotella and Francisella1 (3). Cpf1 or Cas12a is present in both bacteria and archea and is a class 2/type V CRISPR-Cas effector protein which shares some homology with Cas9. For example, Cpf1 and Cas 9 share homologous RuvC-like nuclease domain and Arg-rich region (4). However, key differences between CRISPR/Cpf1 and CRISPR/Cas9 have been noted. Cpf1 requires a 5'-TTTN-3' PAM sequence located upstream to the target DNA and generates a staggered DNA overhang upon cleavage. Additionally, Cpf1 possesses RNase activity which simplifies crRNA or gRNA processing (2).
Using CRISPR-Cas technology, double-stranded DNA breaks may be induced within specific targeted genome sequences (target DNA; protospacer) for insertion or removal of DNA sequences for gene editing applications. To target a specific genomic sequence, gRNAs complementary to specific DNA targets are created. The gRNA will recognize the DNA sequence, and the Cas9 or Cpf1/Cas12a enzyme will cleave the DNA at the targeted location. Once the targeted DNA is removed, the cell's own DNA repair mechanism inserts or removes a DNA sequence resulting in genomic editing. Cpf1 orthologs Acidaminococcus sp Cpf1 (AsCpf1 151kDa) and Lachnospiraceae bacterium Cpf1 (LbCpf1 143kDa) are able to achieve efficient gene editing in human cells (3).
