Regulation of Delta-Aminolevulinic Acid Dehydratase by Krüppel-Like Factor 1

Krüppel-like factor 1(KLF1) is a hematopoietic-specific zinc finger transcription factor essential for erythroid gene expression. In concert with the transacting factor GATA1, KLF1 modulates the coordinate expression of the genes encoding the multi-enzyme heme biosynthetic pathway during erythroid differentiation. To explore the mechanisms underpinning KLF1 action at the gene loci regulating th...

PBX1 as Pioneer Factor: A Case Still Open

Pioneer factors are proteins that can recognize their target sites in barely accessible chromatin and initiate a cascade of events that allows for later transcriptional activation of the respective genes. Pioneer factors are therefore particularly well-suited to initiate cell fate changes. To date, only a small number of pioneer factors have been identified and studied in depth, such as FOXD3/F...

Transcription factor access to chromatin.

The question of how sequence-specific transcription factors access their cognate sites in nucleosomally organized DNA is discussed on the basis of genomic footprinting data and chromatin reconstitution experiments. A classification of factors into two categories is proposed: (i) initiator factors which are able to bind their target sequences within regular nucleosomes and initiate events leadin...

CLOCK:BMAL1 is a pioneer-like transcription factor.

The mammalian circadian clock relies on the master genes CLOCK and BMAL1 to drive rhythmic gene expression and regulate biological functions under circadian control. Here we show that rhythmic CLOCK:BMAL1 DNA binding promotes rhythmic chromatin opening. Mechanisms include CLOCK:BMAL1 binding to nucleosomes and rhythmic chromatin modification; e.g., incorporation of the histone variant H2A.Z. Th...

The forkhead transcription factor FOXK2 acts as a chromatin targeting factor for the BAP1-containing histone deubiquitinase complex

There are numerous forkhead transcription factors in mammalian cells but we know little about the molecular functions of the majority of these. FOXK2 is a ubiquitously expressed family member suggesting an important function across multiple cell types. Here, we show that FOXK2 binds to the SIN3A and PR-DUB complexes. The PR-DUB complex contains the important tumour suppressor protein, the deubi...
