| + | [https://www.uniprot.org/uniprot/BPTF_HUMAN BPTF_HUMAN] Histone-binding component of NURF (nucleosome-remodeling factor), a complex which catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin. Specifically recognizes H3 tails trimethylated on 'Lys-4' (H3K4me3), which mark transcription start sites of virtually all active genes. May also regulate transcription through direct binding to DNA or transcription factors. | ||

| + | Bromodomain and PHD finger containing protein transcription factor (BPTF) is an epigenetic protein involved in chromatin remodelling and is a potential anticancer target. The BPTF bromodomain has one reported small molecule inhibitor (AU1, rac-1). Here, advances made on the structure-activity relationship of a BPTF bromodomain ligand are reported using a combination of experimental and molecular dynamics simulations leading to the active enatiomer (S)-1. Additionally, a ligand deconstruction analysis was conducted to characterize important pharmacophores for engaging the BPTF bromodomain. These studies have been enabled by a protein-based fluorine NMR approach, highlighting the versatility of the method for selectivity, ligand deconstruction, and ligand binding. To enable future analysis of biological activity, cell growth analyses in a panel of cancer cell lines were carried out using CRISPR-Cas9 and (S)-1 to identify cell-based model systems that are sensitive to BPTF inhibition. | ||
