The maternal-to-zygotic transition in #zebrafish is activated by TFs that open #chromatin via enhancers lacking H3K4me2. @MTLeeLab &co identify a parallel pathway that is activated by #enhancers that bear H3K4me2, showing that both act in combination @PLOSBiology https://plos.io/3IFqYMc

This allows condensate behaviour to respond to different inputs, such as lysine #acetylation in IDRs in other CBP domains. It can help to explain how #transcription factors binding to different regions of CBP differentially regulate CBP activity. #enhancers #generegulation #llps #chromatin #imaging #biochemistry #molecularbiology #CellBiology

Hallo all - I guess an introduction might be a good idea!
I'm a mid-career (already!?) group leader, trying to unpick how different aspects of the local environment at #enhancers work together to regulate #transcription and #geneexpression.
We especially like non-coding enhancer #RNA, how their structures and dynamic movements make them functional; how disease mutations affect #eRNA activity and how the enhancer environment affects the #chromatin regulator CBP.
Super-excited to land here!

Amazing work showing that #genetic #disruption of the #kinase module (CDK) of Mediator complex in chimeric #antigen receptor T cell (CAR T) resulted in enhanced effector function and increased #antitumor activity (disruption of CDK module increases core Mediator #chromatin occupancy at #enhancers)
