Limited work has been done on concurrent C-to-G and A-to-G base editing. Here the authors test how a number of chromatin-associated factors affect base editing and show that HMGN1 enhanced the efficiency; by fusing HMGN1 to GBE and ABE they develop a CRISPR-based dual-function A-to-G and C-to-G base editor (GGBE).
