How transcription factors (TFs) cooperate within large protein complexes to allow rapid modulation of gene expression during development is still largely unknown. Here we show that the key haematopoietic LIM-domain-binding protein-1 (LDB1) TF complex contains several activator and repressor componen...

Human naive T cells from peripheral blood were cultured in 24 wells coated with anti-CD3 and anti-CD28 antibodies in the presence or absence of retinoid acid, IL-12, and 1,25 (OH)2 vitamin D3. The T cells were FACS-sorted based on expression of CD3, integrin alpha4beta7, cutaneous lymphocyte antige...

Transcription steps are marked by different modifications of the C-terminal domain of RNA polymerase II (RNAPII). Phosphorylation of Ser5 and Ser7 by cyclin-dependent kinase 7 (CDK7) as part of TFIIH marks initiation, whereas phosphorylation of Ser2 by CDK9 marks elongation. These processes are thou...
