SNPaDomain

SNPaDomain annotates single nucleotide polymorphisms (SNPs) located within human protein domains to support assessment of their potential impact on protein function and disease mechanisms.

Key Features:

• Domain-Based Annotation: Annotates SNPs using structure-based domain assignments from SCOP and sequence-based domain assignments from Pfam.
• Dual Annotation Strategy: Integrates SCOP and Pfam annotations to provide complementary domain assignments and reduce conflicts between structure- and sequence-based mappings.
• Visualization Tools: Maps SNP positions onto protein domains using two-dimensional (2D) and three-dimensional (3D) visualizations to contextualize variant locations relative to domain architecture.
• Integration with External Databases: Cross-references SNPs with Ensembl, dbSNP, OMIM, and SIFT to provide linked genetic, clinical, and functional prediction information.

Scientific Applications:

• Genetic disease research: Enables identification of SNPs within conserved protein domains that may contribute to disease mechanisms.
• Variant prioritization: Supports selection of candidate variants for functional follow-up by combining domain location with cross-referenced dbSNP, OMIM, and SIFT information.
• Structural interpretation: Facilitates interpretation of how SNPs positioned within domain structures might affect protein function using 2D and 3D mappings.

Methodology:

Annotates SNPs from dbSNP with domain information derived from SCOP and Pfam and integrates structural and sequence annotations to produce combined domain-based SNP mappings.
