G9a-Like Protein (GLP) and Small Molecule Inhibitor Complex


Complex of G9a-like protein and BIX-01294, a small molecule inhibitor of G9a and G9a-like protein.

Key Benefits
  • First example of inhibitor bound enzymatic SET domain structure of a protein lysine methyltransferase.
  • May show improved potency and selectivity of the G9a/GLP inhibitor.
Technical Summary

Histone lysine methylation is an important regulator of gene expression and chromatin organization. The small molecule, BIX-01294 (a diazepin-quinazolin-amine derivative), inhibits G9a and G9a-like protein (GLP) histone lysine methyltransferases, which repress transcription by methylating histone H3 at lysine 9 (H3K9). It has been used in the generation of induced pluripotent stem cells. Here, the inhibitor is bound in the substrate peptide groove at the site where the histone H3 residues N-terminal to the target lysine would occupy and resembles the bound confirmation of histone H3 lysine 4 to arginine 8.
