IDEAL

IDEAL catalogs and annotates experimentally verified intrinsically disordered proteins (IDPs) and intrinsically disordered regions (IDRs), providing curated structural and functional information including protean segments, interaction sites, post-translational modification sites, literature references, structural domain assignments, and XML-formatted data.

Key Features:

• Manually Curated Annotations: Detailed, literature-referenced annotations of IDPs and IDRs including interaction sites and post-translational modification sites.
• Protean Segments Identification: Annotation of regions that transition from disordered to ordered states upon binding, identified as molecular recognition elements.
• Functional Region Data Resource: Explicit description of dynamic functional regions within IDPs to support interpretation of their roles in cellular processes and disease.
• Structural Domain Assignments: Inclusion of structural domain annotations alongside disordered region annotations to contextualize protein architecture.
• Data Export Formats: Provision of data downloadable in XML format for integration with external bioinformatics workflows.

Scientific Applications:

• Protein–Protein Interaction Studies: Supports analysis of interaction sites and protean segments involved in molecular recognition and complex formation.
• Functional Characterization of IDPs: Enables investigation of dynamic disordered regions and post-translational modifications in cellular processes and disease mechanisms.
• Annotation-driven Research and Tool Integration: Supplies curated annotations and XML data for downstream bioinformatics analyses and comparative studies.

Methodology:

Manual curation of experimentally verified IDPs and IDRs, annotation of interaction sites, post-translational modification sites, and protean segments, assignment of structural domains, and provision of data in XML format.
