Exploring Manually Curated Annotations of Intrinsically Disordered Proteins with DisProt

Area of Science:

• Biochemistry
• Molecular Biology
• Bioinformatics

Background:

• Intrinsically disordered proteins (IDPs) lack stable tertiary structures but perform vital biological functions.
• Research on IDPs has expanded significantly, focusing on their unique properties and roles.
• DisProt serves as a primary repository for manually curated IDP data from scientific literature.

Purpose of the Study:

• To provide a comprehensive guide on utilizing the DisProt database.
• To explain how to explore and interpret manually curated annotations of intrinsically disordered proteins.
• To demonstrate practical applications of DisProt through search, programmatic access, and data visualization.

Main Methods:

• Literature curation by expert biocurators.
• Web interface and REST API for data retrieval and programmatic access.
• Case study using the p53 protein to illustrate data interpretation.

Main Results:

• DisProt offers up-to-date annotations of intrinsically disordered proteins.
• Users can search and download data via the web interface or API.
• Detailed protocols are provided for accessing and interpreting DisProt entries, including a p53 example.

Conclusions:

• DisProt is an essential resource for researchers studying intrinsically disordered proteins.
• The database facilitates the exploration and understanding of IDP functions and characteristics.
• The guide empowers the scientific community to effectively use DisProt for their research needs.
