제목 Deep learning-based highly accurate prediction of CRISPR-Cpf1 activity
초록 Cpf1 is a recently reported effector endonuclease protein of the class 2 CRISPR-Cas system. Here, we developed a method for evaluating Cpf1 activity based on target sequence composition in mammalian cells in a high-throughput manner. using this approach, we determined protospacer adjacent motif sequences of two Cpf1 nucleases, from Acidaminococcus sp. BV3L6 and Lachnospiraceae bacterium ND2006 (AsCpf1 and LbCpf1, respectively), and target sequence-dependent activity profiles of AsCpf1. Based on these data sets, we developed Seq-deepCpf1, a deep learning-based algorithm, which outperformed conventional machine learning-based algorithms. Subsequent fine-tuning of Seq-deepCpf1 using data sets of AsCpf1-induced indel frequencies at endogenous target sites with chromatin accessibility information enabled the development of DeepCpf1. We provide DeepCpf1 as a web tool, which predicts AsCpf1 activities at endogenous target sites with unprecedentedly high accuracy.
