Epigenetic regulators of gene expression and chromatin state include so-called writers, erasers, and readers of chromatin modifications.Well-characterized examples of reader domains include bromodomains typically binding acetyllysine and chromatin organization modifier (chromo), malignant brain tumor (MBT), plant homeodomain (PHD), and Tudor domains generally associating with methyllysine. Research on epigenetic readers has been tremendously influenced by the discovery of selective inhibitors targeting the bromodomain and extraterminal motif (BET) family of acetyl-lysine readers. The human genome encodes 46 proteins containing 61 bromodomains clustered into eight families. Distinct experimental approaches are used to identify the first BET inhibitors, GSK 525762A and (+)-JQ-1.

The Polycomb group (PcG) protein, enhancer of zeste homologue 2 (EZH2), has an essential role in promoting histone H3 lysine 27 trimethylation (H3K27me3) and epigenetic gene silencing. This function of EZH2 is important for cell proliferation and inhibition of cell differentiation, and is implicated in cancer progression. Cyclin-dependent kinases regulate epigenetic gene silencing through phosphorylation of EZH2. In many types of cancers including lymphomas and leukemia, EZH2 is postulated to exert its oncogenic effects via aberrant histone and DNA methylation, causing silencing of tumor suppressor genes.

p300/CBP is not only a transcriptional adaptor but also a histone acetyltransferase.

    		Inhibitor 98.82%
    CBP/p300 ligand 3 is a target protein ligand of CBPD-268 (HY-161369). CBP and p300 are two proteins with histone acetyltransferase (HAT) activity, and CBP and p300 play key roles in regulating biological processes such as gene expression, cell proliferation, differentiation and DNA repair. Through its acetyltransferase activity, CBP/p300 can acetylate histones and other proteins, thereby regulating chromatin structure and gene expression. CBP/p300 ligand 3 regulates the function of CBP/p300 by binding to a specific domain of the CBP/p300 protein (the bromine domain or HAT domain), inhibiting its enzyme activity or altering its interactions with other proteins (transcription factors). CBP/p300 ligand 3 can be used in cancer, neurodegenerative diseases and other disease models associated with abnormal CBP/p300 function.
