	Roles of histone H3 lysine methylation in the gene expression regulation Čizmazia, Viliam ; Veverka, Václav (advisor) ; Ormsby, Tereza (referee) Viliam Čizmazia Roles of histone H3 lysine methylation in the gene expression regulation Abstract Histone post-translational modifications play a key role in epigenetic regulation of chromatin land- scape and various cellular functions. They can directly mediate interactions between DNA and histones, but also represent recognition signals for specific reader proteins. A particular type of these modifications, lysine methylation, marks a number of specific sites within the terminal as well or globular regions of histone proteins and encodes for various instructions for DNA-related processes such as gene transcription. The profiles of individual lysine methylations are regulated by specific methyltransferases (writers) and antagonizing demethylases (erasers). Their deregula- tion is often associated with diseases such as developmental abnormalities or cancer. For this rea- son, a number of histone-modifying enzymes are considered attractive therapeutic targets. This review is focused on key players and mechanisms underlying the deposition of the most important histone H3 lysine methylations, their genomic distribution and contextual roles in transcriptional events. In addition, it highlights the importance of structure-based approaches in exploring the molecular details behind the activity of histone... Detailed record
