This review focuses on histone methyltransferases SUV4-20H1 and SUV4-20H2, which catalyze H4K20 di- and tri-methylation, and their roles in various biological processes such as DNA repair, cell cycle regulation, and DNA replication. It also outlines the pathological conditions associated with H4K20me2/3 misregulation due to mutations or aberrant expression of SUV4-20H1 or SUV4-20H2, and critically analyzes the data supporting these functions for future research.
The post-translational modification of histone tails is a dynamic process that provides chromatin with high plasticity. Histone modifications occur through the recruitment of nonhistone proteins to chromatin and have the potential to influence fundamental biological processes. Many recent studies have been directed at understanding the role of methylated lysine 20 of histone H4 (H4K20) in physiological and pathological processes. In this review, we will focus on the function and regulation of the histone methyltransferases SUV4-20H1 and SUV4-20H2, which catalyze the di- and tri-methylation of H4K20 at H4K20me2 and H4K20me3, respectively. We will highlight recent studies that have elucidated the functions of these enzymes in various biological processes, including DNA repair, cell cycle regulation, and DNA replication. We will also provide an overview of the pathological conditions associated with H4K20me2/3 misregulation as a result of mutations or the aberrant expression of SUV4-20H1 or SUV4-20H2. Finally, we will critically analyze the data supporting these functions and outline questions for future research.
