Abstract:
MRG15 is a transcription factor containing the methyl-lysine reader chromodomain. Despite its involvement in different physiological and pathological states, to date the role of this protein has not been fully elucidated due to the lack of a specific and potent chemical probe.In this work, we report the development of a microscale thermophoresis (MST)-based assay for the study of MRG15-ligand binding interactions. After the development, the assay was validated using a small focused library and UNC1215 as the reference compound, to yield the identification of 10 MRG15 ligands with affinities ranging from 37.8 nM to 59.1 µM.Hence, our method is robust, convenient, and fast and could be applied to other methylation reader domain-containing proteins for the identification of new chemical probes.
