Summary
Spatially adjacent transcription factor binding site-clustered regions (SATs) connect distal elements, regulating genes through spatial proximity. This model reveals SATs frequently regulate genes located between clustered regions, not downstream.
Area of Science:
- Genomics
- Molecular Biology
- Bioinformatics
Background:
- Transcription factor binding sites (TFBSs) cluster in the human genome, forming regulatory regions.
- Gene transcription requires dynamic chromatin configurations between promoters and distal regulatory elements.
Purpose of the Study:
- Propose a novel regulatory model, spatially adjacent TFBS-clustered regions (SATs).
- Investigate the role of SATs in gene regulation using high-resolution Hi-C data.
Main Methods:
- Utilized high-resolution Hi-C data to identify spatial proximity between TFBS-clustered regions.
- Reconstructed chromosomal conformation using the ShRec3D algorithm in H1 human embryonic stem cells.
Main Results:
- SATs were less frequent at gene promoters but more frequent overall compared to isolated TFBS-clustered regions.
- Multiple distal TFBS-clustered regions form SATs to regulate genes.
- Genes regulated by SATs were often located between the clustered regions.
Conclusions:
- The SAT model provides a new framework for understanding gene regulation by clustered TFBSs.
- Spatial proximity plays a crucial role in coordinating distal regulatory elements.

02:02Cis-regulatory Sequences
12.0K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

02:13Cooperative Binding of Transcription Regulators
7.4K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome. Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

12.7K
Chromatin immunoprecipitation, or ChIP, is an antibody-based technique used to identify sites on DNA that bind to transcription factors of interest or histone proteins. It also helps determine the type of histone modifications such as acetylation, phosphorylation, or methylation.
Types of ChIP
ChIP can be divided into two types - X-ChIP and N-ChIP. X-ChIP involves in vivo cross-linking of histones and regulatory proteins to DNA, fragmenting the DNA by sonication, and isolating the protein-DNA...
