MISCAST

MISCAST maps missense variants onto protein sequences and three-dimensional structures to support analysis of their potential effects on protein structure and function.

Key Features:

• Variant mapping: Maps missense variants to protein sequence positions and corresponding three-dimensional residues to contextualize substitutions.
• Feature integration: Aggregates structural and functional features from multiple databases and aligns them with protein residues.
• Functional annotation: Annotates variants with information relevant to macromolecular interactions and cellular signaling pathways to assess potential disruptions.
• Spatial pathogenic clustering: Identifies variants located in the protein core or within three-dimensional clusters associated with pathogenic mutations.
• Exportable annotations and structures: Provides annotated variant data and protein structure files for download to enable offline analysis.

Scientific Applications:

• Variant effect interpretation: Assess how amino acid substitutions affect protein structure and function at the molecular level.
• Interaction disruption analysis: Evaluate whether variants may disrupt essential macromolecular interactions or cellular signaling pathways.
• Structural localization: Determine whether variants reside in the protein core or in three-dimensional clusters associated with pathogenic mutations.
• Offline structural analysis: Perform detailed examination of missense variants using downloaded annotated data and protein structures.

Methodology:

Aggregates structural and functional features from multiple databases, maps missense variants onto protein sequence and three-dimensional structures, aligns and displays these features alongside variants on protein structures, and provides annotated data and structure files for download.
