MS0124 is a Potent and Selective Inhibitors for G9a-Like Protein (GLP) Lysine Methyltransferase. MS0124 was 34-fold more selective for GLP (IC50 =_x000D_
13 ± 4 nM) over G9a (IC50 = 440 ± 63 nM). G9a-like protein (GLP) and G9a are highly homologous protein lysine methyltransferases (PKMTs) sharing approximately 80% sequence identity in their catalytic domains. GLP and G9a form a heterodimer complex and catalyze mono- and dimethylation of histone H3 lysine 9 and nonhistone substrates
