The new ultra-low input CUT&RUN (uliCUT&RUN) technique allows for genome-wide mapping of DNA binding proteins from single cells and individual pre-implantation mouse embryos. This enables researchers to focus on cell heterogeneity and studies from limited biological samples.
Researchers developed a high-throughput method to screen and categorize transcription factors based on their ability to displace nucleosomes. The study identified both new and previously known nucleosome-displacing factors, which tend to be highly abundant in the nucleus and bind tightly to DNA.
Researchers at Stowers Institute for Medical Research developed a new method to precisely map individual transcription factor binding sites in the genome. The technique, called ChIP-nexus, uses an enzyme to trim back DNA fragments to the spot where transcription factors bind, providing more accurate information than existing methods.
Researchers discovered that transcription factor binding sites are not conserved across 300 million years of evolution. Despite this, these proteins still regulate liver-specific genes in vertebrates. This study highlights the plasticity of gene regulation and its implications for disease mechanisms.
A recent study found that many interactions detected by ChIP-chip are functionally irrelevant. The researchers discovered a clear relationship between the number of factor molecules bound at a given site and its role in gene regulation, suggesting that DNA sites with low-level binding may play no role in regulating gene expression.
Researchers identified a large fraction of functional transcription factor binding sites near human gene transcriptions, challenging traditional views of complex organism regulation. This discovery could aid in identifying transcriptional networks underlying cellular processes and diseases.
STAT proteins play a key role in regulating gene expression by phosphorylating specific sequences, leading to transcriptional activation. This process is essential for various cellular processes, including proliferation and differentiation.
