Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.
Dot1l and its H3K79 methyltransferase activity are required for thermogenesis, and Dot1l is recruited by Zc3h10 to its targets genes to alter chromatin accessibility to activate the thermogenic gene program.
Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.
The structure of the yeast RSC complex, a member of the SWI/SNF chromatin remodeling family, determined by cryo-electron microscopy, reveals a conserved structural core and the mode of nucleosome engagement.
E3 ubiquitin ligase Bre1-induced H2B monoubiquitination is epigenetically important for recruiting replication factor Mcm10 and cohesion establishment factors Ctf4, Ctf18 and Eco1 to early replication origins to establish sister chromatid cohesion.
The histone chaperone FACT and the deubiquitinating enzyme Ubp10 act in concert to remove ubiquitin from histone H2B in nucleosomes, and likely coordinate nucleosome assembly during DNA replication and transcription.
