MACSIMS

MACSIMS integrates multiple sequence alignments and heterogeneous biological data to annotate and propagate structural, functional, and evolutionary features within protein families.

Key Features:

• Multiple Sequence Alignment Framework: Uses multiple sequence alignments as the foundational framework for integrating diverse datasets across protein families.
• Integration of Knowledge-based and Ab Initio Methods: Combines knowledge-based annotations with ab initio sequence analysis methods to enhance sequence characterization.
• Automatic Data Retrieval: Automatically retrieves structural and functional information from public databases.
• Homologous Region Identification and Feature Propagation: Identifies homologous regions within alignments and propagates sequence features from known to unknown sequences with reported specificity >99%.
• Enhanced Feature Characterization: Increased the number of associated sequence features by 60% in a large-scale evaluation of 100 proteins linked to human genetic diseases.
• XML Format Output: Generates XML output files to facilitate automatic parsing of results.
• Comprehensive Structural, Functional, and Evolutionary Analysis: Provides analyses spanning structural, functional, and evolutionary levels within protein families.

Scientific Applications:

• Characterization of Disease-associated Mutations: Enhances annotation and interpretation of mutations linked to human genetic diseases by expanding associated sequence features and enabling reliable feature propagation.
• Annotation of Uncharacterized Proteins: Transfers structural and functional annotations to uncharacterized sequences via alignment-based propagation of features.
• Systems-level Integration: Integrates genomics, proteomics, and transcriptomics data within protein family alignments for systems-level studies.

Methodology:

Uses multiple sequence alignment as the integration framework; combines knowledge-based and ab initio sequence analysis; automatically retrieves structural and functional data from public databases; identifies homologous regions and propagates sequence features with validation reporting specificity >99%; outputs results in XML format.
