Background: Cpf1

Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated endonuclease from Prevotella and Francisella 1, Cpf1, also known as Cas12a, is a  1200-1500 amino-acids long monomeric protein that belongs to the CRISPR/Cas system (1, 2), an adaptive immune system of prokaryotes that has now become a powerful tool for genome editing (3). CRISPR/Cpf1 belongs the class II (type 5) of the CRISPR/Cas system that is defined by a single-subunit effector (4). Cpf1 has recently emerged as an alternative for Cas9, due to its distinct features (2, 5) such as the ability to target T-rich motifs, no need for trans-activating crRNA, inducing a staggered double-strand break and potential for both RNA processing and DNA nuclease activity. In addition, Cpf1 is able to process more structured pre-CRISPR/RNA(crRNA) molecules into mature crRNAs (6) which allows the possibility to use both mature or pre-crRNA for genome editing purposes(7). All these features make the CRISPR-Cpf1 system a valuable genome-engineering tool (8). CRISPR-Cpf1(Cas12a) has been successfully used to edit genomes in mammalians cells (2), plants (9), mice (10), Drosophila (11) and recently zebrafish and Xenopus (7). Two Cpf1 orthologs have been commonly used for genome editing in different organisms: AsCpf1 and LbCpf1, which are derived from Acidaminococcus sp. BV3L6 and Lachnospiraceae bacterium ND2006, respectively (8).The attached nuclear localization signals (NLSs) on the chimeric protein ensures nuclear compartmentalization in cells during gene editing (12).
