Abstract

Specific chromatin marks keep master regulators of differentiation silent, yet poised for activation by extracellular signals. We report that nodal TGF-β signals use the poised histone mark H3K9me3 to trigger differentiation of mammalian embryonic stem cells. Nodal receptors induce the formation of companion Smad4-Smad2/3 and TRIM33-Smad2/3 complexes. TRIM33-Smad2/3 binds the histone marks H3K9me3 and K18ac on the promoters of mesendoderm regulators Gsc and Mixl1. Binding is through the PHD-Bromo cassette of TRIM33. In the crystal structure of this cassette bound to histone H3 peptides, PHD recognizes K9me3 and Bromo an adjacent K18ac. Binding of TRIM33-Smad2/3 to H3K9me3 displaces the chromatin compacting factor HP1γ and makes nodal response elements accessible to Smad4-Smad2/3 for Pol II recruitment. In turn, Smad4 increases K18 acetylation to augment TRIM33-Smad2/3 binding. Thus, nodal cues use the H3K9me3 mark as a platform to switch master regulators of stem cell differentiation from the poised to the active state.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
