Figure Lengend Snippet: A. Structure of human CBX8, CBX7, CBX1 PCD and BAHCC1 BAH domains (RCSB PDB 3I91, 4X3K, 6D07 and 6VIL) with hydrophobic binding pocket residues highlighted in light blue. Residue substitutions in engineered variants (sea green) are as follows: dCBX7 - F11A; CBX7.VD - Q9D, K33E; CBX1eR - K43A, D59F. B. ELISA binding results for CBX8 fusion proteins. C. ELISA binding results for wild-type and engineered H3K27me3-binding fusion proteins. Dots = mean A450 from 3 technical replicate wells, bars = mean of 2 replicate TX-TL products, error bars = standard deviation.
