Introduction: Unlocking the Secrets of Gene Regulation
In the ever-evolving world of genomics and bioinformatics, understanding the intricate mechanisms of gene expression is crucial. One of the key elements in this process is the cis-regulatory element non-coding DNA sequences that regulate the transcription of neighboring genes.
This is where cisRED comes in.
cisRED (cis-Regulatory Element Database) is a robust, genome-wide analytical platform built to help researchers uncover conserved regulatory motifs across species. By leveraging evolutionary conservation and gene co-expression data, cisRED delivers a curated set of high-confidence regulatory elements for the scientific community.
cisRED is a fully automated system designed to identify regulatory sequences in the non-coding regions upstream of genes. These upstream regions are particularly important because they often contain transcription factor binding sites (TFBS) the control switches that regulate whether a gene is turned on or off.
To ensure accuracy and relevance, cisRED focuses on:
- 1.5 kb upstream of each Transcription Start Site (TSS)
- Filtering out repetitive elements
- Detecting statistically significant motifs
- Using comparative genomics to analyze orthologous genes across multiple species
This approach allows cisRED to offer computationally predicted regulatory motifs that are conserved and biologically relevant.
Whether you're working in molecular biology, genomics, systems biology, or computational biology, cisRED provides tools that are highly valuable for:
cisRED helps scientists identify transcription factor binding sites involved in cell-specific or condition-specific gene expression.
Comparative Genomics
By comparing conserved motifs across species, cisRED supports the study of evolutionarily conserved regulatory mechanisms.
Bioinformatics Tool Development
Developers can integrate cisRED data into new tools or pipelines aimed at motif analysis, gene network prediction, or regulatory sequence annotation.
