Summary
This study introduces tfTarget, a computational tool for analyzing transcription regulation. It maps transcriptional regulatory elements and target genes responding to transcription factors using sequencing data.
Area of Science:
- Genomics
- Computational Biology
- Molecular Biology
Background:
- Run-on sequencing assays (GRO-seq, PRO-seq, ChRO-seq) profile transcription activity of regulatory elements and genes.
- Changes in transcription factor activity under different biological conditions affect both regulatory elements and target genes.
Purpose of the Study:
- To develop a computational pipeline, tfTarget, for predicting transcriptional regulatory elements and target genes associated with specific transcription factors.
- To demonstrate the application of the web-based tfTarget tool for analyzing transcription regulation using run-on sequencing data.
Main Methods:
- Modeling differences between biological conditions to identify TF-responsive elements and genes.
- Utilizing run-on sequencing data (e.g., GRO-seq, PRO-seq, ChRO-seq).
- Developing a web-based interface for the tfTarget pipeline.
Main Results:
- The tfTarget pipeline successfully predicts putative transcriptional regulatory elements and target genes.
- Demonstrated the ability to map transcription regulation in response to varying biological conditions.
- The web-based tool facilitates the analysis of complex transcription regulatory networks.
Conclusions:
- tfTarget provides a novel computational approach for understanding transcription factor-mediated gene regulation.
- The tool enhances the analysis of high-throughput sequencing data for regulatory element and gene profiling.
- Web-based tfTarget enables accessible mapping of transcription regulation.

10.3K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

10.0K
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...

01:17Transcription
23.8K
Transcription is the synthesis of RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in correctly synthesizing messenger RNA (mRNA). Transcriptional regulation is responsible for the differentiation of different types of cells and often for the proper cellular response to environmental signals.

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

01:23Regulation of Expression at Multiple Steps
976
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
