GSK J4 is a chemical compound that functions as a potent and selective inhibitor of the histone demethylase KDM6B (JMJD3). It acts by binding to the active site of KDM6B, preventing the demethylation of histone H3 lysine 27 (H3K27). This inhibition leads to an accumulation of H3K27me3, resulting in the repression of genes involved in various cellular processes. By modulating the epigenetic landscape, GSK J4 may influence gene expression patterns and cellular differentiation. Its mechanism of action involves disrupting the balance of histone methylation, thereby impacting the transcriptional regulation of specific genes. In development setting, GSK J4 is utilized to investigate the role of KDM6B in epigenetic regulation and to the downstream effects of histone methylation changes on cellular function.
