Cellular target proteins for the published G9a selective<br />

methyltransferase inhibitors UNC0638 and BIX-01294 were<br />

identified in human CML (K562) cells<br />

Comparison with published in vitro data revealed known as well<br />

as previously unknown target proteins for both compounds<br />
