Pyntheon

Pyntheon analyzes posttranslational modifications (PTMs) and mutations across 83 model organisms to map PTM–mutation overlaps and assess impacts on functional regions and phenotypes.

Key Features:

• Extensive Organism Coverage: Contains PTM and mutation data for 83 model organisms.
• Functional Region Analysis: Determines whether PTM sites overlap mutated residues and whether modifications occur within functional regions such as domains or structural areas.
• Mutation–Modification Correlation: Evaluates how mutations may influence PTMs and how PTMs may relate to observed mutations.
• Phenotypic Impact Assessment: Integrates modification and mutation data to support interpretation of potential effects on phenotypes.
• Identifier-based Mapping: Accepts UniProt IDs or lists of proteins to retrieve mapped PTM and mutation site information.
• Implementation and Data Sources: Python-based and built on curated proteomics data integrated with existing databases of PTMs and mutation data.

Scientific Applications:

• Proteomics: Mapping PTMs and mutations to proteins to support proteome-level analyses.
• Genomics and Functional Biology: Linking genetic variation to changes in protein modification and function.
• Evolutionary Biology: Comparing PTM and mutation patterns across 83 model organisms to study evolutionary conservation.
• Disease Research: Identifying mutation–PTM relationships relevant to pathologies.
• Drug Discovery: Informing target selection and mechanism studies by highlighting modification-sensitive residues.

Methodology:

Pyntheon integrates curated proteomics data with existing PTM and mutation databases, maps PTMs and mutations to UniProt IDs or provided protein lists, and is implemented in Python.
