Plant homeodomain finger protein 1 (PHF1) is an accessory component of the gene silencing complex polycomb repressive complex 2 and recognizes the active chromatin mark, trimethylated lysine 36 of histone H3 (H3K36me3). In addition to its role in transcriptional regulation, PHF1 has been implicated as a driver of endometrial stromal sarcoma and fibromyxoid tumors. We report the discovery and characterization of UNC6641, a peptidomimetic antagonist of the PHF1 Tudor domain which was optimized through in silico modeling and incorporation of non-natural amino acids. UNC6641 binds the PHF1 Tudor domain with a Kd value of 0.96 ± 0.03 μM while also binding the related protein PHF19 with similar potency. A crystal structure of PHF1 in complex with UNC6641, along with NMR and site-directed mutagenesis data, provided insight into the binding mechanism and requirements for binding. Additionally, UNC6641 enabled the development of a high-throughput assay to identify small molecule binders of PHF1.
