TFmodeller models protein-DNA interactions using homology, aiding discovery of molecular details for transcriptional regulation. This tool provides evolutionary contact matrices and binding interface models for researchers.
Area of Science:
- Molecular Biology
- Bioinformatics
- Structural Biology
Background:
- Protein-DNA interactions are crucial for cellular processes like transcriptional regulation.
- Many protein-DNA interactions' molecular details are yet to be elucidated.
- The Protein Data Bank (PDB) contains experimentally determined protein-DNA complex structures.
Purpose of the Study:
- To develop a computational tool, TFmodeller, for modeling protein-DNA interfaces.
- To leverage existing structural data for predicting novel protein-DNA interactions.
- To provide researchers with detailed models of putative protein-DNA binding interfaces.
Main Methods:
- TFmodeller utilizes homology to model protein-DNA interfaces.
- It exploits information from the Protein Data Bank (PDB).
- The tool's complex library is updated weekly and available for download.
Main Results:
