WebLysine and arginine residues both contain amino groups, which confer basic and hydrophobic characteristics. Lysine is able to be mono-, di-, or trimethylated with a methyl group replacing each hydrogen of its NH3+ group. With a free NH2 and NH2+ group, arginine is able to be mono- or dimethylated. WebMar 21, 2024 · Here, we show that lysine 49 (K49) of β-catenin is trimethylated (β-catMe3) by Ezh2 or acetylated (β-catAc) by Cbp. Significantly, β-catMe3 acts as a transcriptional co-repressor of the neuronal differentiation genes sox1 and sox3 , whereas β-catAc acts as a transcriptional co-activator of the key mesodermal differentiation gene t-brachyury ( t-bra ).
