The Bromodomain Ligand 2 is peptide histone H3 (1-21), acetylated at lysine 14. It contains a C-terminal GG linker, followed by a biotinylated Lys. Bromodomains function as acetyl-lysine binding domains, and bromodomain/acetyl-lysine recognition can regulate histone modification, DNA replications, chromatin remodeling, and gene transcription. This peptide is suitable for use as a ligand for several bromodomains including ATAD2 and BAZ2B.
