Role of the nuclear periphery in chromatin organization
Discover how and why the spatial organization of chromatin impacts gene expression https://www.youtube.com/watch?v=lK_5EhFux0s
It is becoming increasingly clear that the 3D organization of the genome within the nucleus has a profound influence on gene expression and several functional nuclear domains have been defined including the nuclear periphery. Many proteins components of the nuclear periphery have been described over the 10 last years (left side of the figure) and mutants affecting these proteins alter nuclear size and shape (right side of the figure) with for some of them significant impact on gene transcription. Despite the fact that the protein composition differs between animals and plants, the concept that the nuclear periphery is a functional interface influencing gene expression is conserved. Yet, the protein composition of the nuclear periphery in plants is still poorly documented and this motivated our research efforts to better understand the impact of the nuclear periphery on chromatin organization and transcription regulation.
