F. novicida dCpf1 (dCas12a) protein

Endonuclease dead version of the Francisella novicida cpf1 gene [1]

The Fn-dCpf1 protein can highly efficient bind target DNA, but due to mutations in the DNA cleavage domains it is unable to cleave target DNA. The Fn-dCpf1 protein can be used as a transcriptional regulator for gene expression by blockage of RNA polymerase initiation (targeting a promoter region) or RNA polymerase elongation (targeting the coding sequence). The DNA cleavage domains of the F. novicida Cpf1 protein were inactivated by the introduction of two mutations in the RuvC I and the RuvC II domains (D917A, E1006A) [2].
