Comparing ATP Binding Sites in Kinases
Author Information
Author(s): Dreher J, Baumann K
Primary Institution: University of Technology
Hypothesis
The study aims to develop structure-based ATP binding site descriptors that reflect the pharmacological profile of a predefined set of inhibitor molecules.
Conclusion
The MIF-based descriptors effectively characterize the geometry of hot spots on proteins, aiding in optimizing the selectivity profile of compounds.
Supporting Evidence
- The study used a dataset of 38 kinase inhibitors with experimental data against 90 human kinases.
- Performance was measured by ROC enrichments and Neighborhood Behavior criteria.
- MIF-based descriptors are independent of sequence information.
Takeaway
Scientists are trying to understand how different drugs work on similar proteins, which can help make better medicines.
Methodology
A three-step procedure involving sequence alignment, superimposition of kinase structures, and calculation of molecular interaction field descriptors was used.
Limitations
Sequence-based methods cannot detect unrelated kinases with similar pharmacological profiles.
