FunTaxIS-lite

FunTaxIS-lite implements taxon-based constraints on Gene Ontology (GO) terms to define and refine protein functions across diverse organisms.

Key Features:

• Taxon-based GO constraints: Implements constraints on Gene Ontology (GO) terms that delineate the specific functions an organism or taxon can perform.
• Constraint generation and propagation: Uses a set of rules to generate and propagate constraints through the taxonomic hierarchy and the GO graph.
• Extension of GO Consortium constraints: Expands the constraints provided by the Gene Ontology Consortium by an average of 300%.
• Improved function prediction precision: Reduces errors introduced by automatic annotation algorithms and enhances the precision of predicted protein functions.
• Annotation correction: Identifies and corrects inconsistent protein annotations in sequence annotation databases.

Scientific Applications:

• Protein function annotation refinement: Refines GO-based protein annotations by applying taxon-specific constraints.
• Cross-taxon comparative analysis: Enables comparison of protein functions across diverse organisms with taxon-aware specificity.
• Database curation and quality control: Supports detection and correction of inconsistent annotations in biological databases.

Methodology:

A sophisticated set of rules generates and propagates taxon-based constraints across the taxonomic hierarchy and the GO graph.
