- W2076018308 abstract "Embryonic stem (ES) cells, like all cell types, are defined by their unique transcriptional signatures. The ability of ES cells to self-renew or exit the pluripotent state and enter differentiation requires extensive changes in their transcriptome and epigenome. Remarkably, transcriptional programs governing each cell fate must remain sufficiently malleable so that expression of only a handful of transcriptional activators can override the pre-existing state by collaborating with an unexpectedly elaborate collection of coactivators to specify, restrict and stabilize the new state. Here, we discuss recent advances in our understanding of how the same coactivator can interpret multiple lines of information encoded by different activators and integrate signals from diverse regulators into stem cell-specific transcriptional outputs.

Known modifications of histones include methylation, acetylation, phosphorylation, ubiquitination, SUMOylation, citrullination, glycosylation, propionylation, butyrylation, proline cis–trans isomerization, ADP-ribosylation, and proteolysis. a zinc-coordinating domain of 50–80 amino acids that anchors PHD-containing proteins to unmodified or various forms of modified lysines on the histone H3 tail (H3K4me3, H3K9me3, H3K4me0). a protein that recognizes and binds a specific DNA motif in the promoter and/or enhancer region of a given gene, and can mediate gene activation or repression. a protein or protein complex that mediates transcriptional activation or repression via interaction with general and/or sequence-specific transcription factors. a transcriptional cofactor that enhances transcription of a target gene. a transcriptional cofactor that represses transcription of a target gene." @default.
