This study introduces mSTRAP, an automated workflow using natural language processing (NLP) to extract mutation data from biomedical literature. The system aids in protein structure annotation and visualization, streamlining complex data management tasks.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Biomedical Informatics

Background:

  • Mutation information is fragmented across diverse data sources.
  • Manual extraction of mutation data is labor-intensive and error-prone.

Purpose of the Study:

  • To develop an automated workflow for mining and visualizing mutation annotations from biomedical literature.
  • To integrate mutation data with protein structure information for enhanced analysis.

Main Methods:

  • Utilized natural language processing (NLP) for automated mutation extraction from full-text literature.
  • Developed a formal OWL-DL ontology for data aggregation and management.
  • Integrated a visualization subsystem (mSTRAPviz) and a homology modeling pipeline for structure generation.

Main Results:

  • mSTRAP successfully automates the retrieval, extraction, processing, and visualization of mutation annotations.
  • The system facilitates the coordination of information into a structured ontology.
  • Generated theoretical protein models for mutated sequences lacking experimental structures.

Conclusions:

  • mSTRAP provides a workable solution for automating tedious mutation annotation workflows.
  • The system enhances the accessibility and usability of mutation data for research.
  • The developed ontology and visualization tools support efficient data management and exploration.
