Loss of SUMOylation drives aberrant PRC1 clustering and 3D genome rewiring independent of H3K27me3
Abstract. Polycomb repressive complex 1 (PRC1) forms nuclear condensates that organize target chromatin domains. SUMOylation modulates PRC1 clustering, but

Modeling the spatial organization of replicated chromosomes in yeast reveals a loose asymmetric cohesion between sister chromatids
Abstract. Following DNA replication, cohesion maintains sister chromatids (SCs) in spatial proximity with a certain degree of alignment. This tethering, me

Kinetic properties of optogenetic site-specific DNA recombination by LiCre-loxP
Summary: We characterize the properties of LiCre, which, in response to blue light, can switch on or off whatever gene is close to a specific DNA sequence called LoxP.
