Web-Based Computational Tools for Base Editors

AbstractCRISPR-based base editors are efficient genome editing tools for use in base correction. Currently, there are various versions and types of base editors with different substitution patterns, editing windows, and protospacer adjacent motif (PAM) sequences. For the design of target sequences, consideration of off-target sequences is required. In addition, for assessment of base editing outcomes in bulk populations, the analysis of high-throughput sequencing data is required. Several web browser-based computation programs have been developed for the purpose of target design and NGS data analysis, especially for users with less computational knowledge. In this manuscript, depending on the purpose of each program, we provide an explanation of useful tools including BE-Designer for design of targets and BE-Analyzer for analysis of NGS data that were developed by our group, CRISPResso2 for analysis of NGS data developed by Luca Pinello group, DeepBaseEditor for prediction of target efficiency developed by Hyongbum Henry Kim group, and BE-Hive for prediction of target outcome developed by David Liu group.Key wordsBase editors (BEs)Web toolComputational tools for base editors
