Latest Developments in the Research and Development of BET inhibitor

BET (Bromodomain and Extra-Terminal) proteins play a crucial role in the regulation of gene expression in the human body. These proteins are involved in the recognition and binding of acetylated lysine residues on histone proteins, which are responsible for controlling gene transcription. By binding to these acetylated lysine residues, BET proteins facilitate the recruitment of transcriptional machinery and other regulatory proteins to specific gene loci, thereby influencing gene expression. This makes BET proteins important regulators of various cellular processes, including cell growth, differentiation, and inflammation. Due to their involvement in gene regulation, BET proteins have emerged as potential therapeutic targets for various diseases, including cancer and inflammatory disorders.
