KRDS

KRDS evaluates drug resistance mutations in kinases relevant to anti-cancer therapies by generating mutant kinase structural models and performing ligand docking to assess effects on kinase-ligand interactions.

Key Features:

• Mutation input processing: Processes lists of kinase point mutations for downstream structural and docking analysis.
• Mutant kinase structural modeling: Generates structural models for mutant kinase proteins using protein structure modeling methods.
• Ligand docking simulations: Performs ligand docking simulations between generated mutant kinase models and potential drug molecules.
• Docking score analysis: Computes and compares docking scores to quantify changes in predicted binding affinity caused by mutations.
• Conformational analysis: Analyzes ligand conformations and docking poses to assess mutation-induced alterations in binding modes.

Scientific Applications:

• Mechanistic investigation: Elucidates how specific kinase mutations alter kinase-ligand binding mechanisms and conformations.
• Resistance inference: Infers the impact of mutations on drug binding to identify mutations likely to confer drug resistance.
• Therapeutic guidance: Guides development and optimization of therapeutic strategies to overcome kinase-associated drug resistance in anti-cancer contexts.

Methodology:

KRDS generates structural models of mutant kinases, conducts ligand docking simulations with drug molecules, and analyzes changes in docking scores and ligand conformations to assess effects of mutations on kinase-ligand interactions.
