HotSpot3D

HotSpot3D identifies mutation hotspots in protein three-dimensional structures, maps spatially proximal variants including data from 33 different cancers cataloged in the Cancer Genome Atlas (TCGA), and analyzes their potential effects on protein function.

Key Features:

• Mutation Hotspot Identification: Pinpoints regions on protein 3D structures where mutations cluster to facilitate analysis of potential impacts on protein function and stability.
• Broad Variant Support: Accepts any variant classification, not limited to missense mutations, enabling analysis across diverse mutation types.
• Spatial Clustering: Identifies and groups mutations that are spatially proximal on the protein structure to detect mutational hotspots.
• Cancer Database Integration: Integrates proximal mutation data from 33 different cancers cataloged in the Cancer Genome Atlas (TCGA) for cross-cancer analysis.
• Visualization Capability: Generates visual representations of mutational clusters on protein 3D structures to support structural interpretation.
• Data Pre-processing: Performs initial processing of mutation datasets to prepare them for downstream clustering and visualization.

Scientific Applications:

• Protein structure-function analysis: Uses hotspot mapping to investigate how clustered mutations affect protein function and stability.
• Oncology and cancer genomics: Analyzes TCGA-derived mutations across 33 cancers to characterize cancer-associated mutational landscapes.
• Pathogenesis inference: Supports identification of structurally clustered mutations that may indicate mechanisms of disease.
• Therapeutic target identification: Highlights candidate sites for therapeutic intervention based on spatial mutation clustering.
• Genetics and structural biology research: Applies to studies requiring analysis of diverse mutation types in a structural context.

Methodology:

Data pre-processing of mutation datasets, clustering analysis to identify spatially proximal mutation groups, and visualization of mutational clusters on protein 3D structures.
