cncRNAdb

cncRNAdb provides a manually curated database of experimentally validated RNAs that exhibit both protein-coding and noncoding functions (dual-function RNAs, binary functional RNAs, bifunctional RNAs or cncRNAs) to support analysis and annotation of their molecular roles.

Key Features:

• Manual curation: Entries are manually curated to record experimentally validated functions of RNAs.
• Experimental support statistics: The database contains approximately 2,600 experimentally supported functions across more than 2,000 distinct RNAs.
• RNA types included: The collection comprises over 1,300 translated ncRNAs and over 600 untranslated mRNAs.
• Multi-species coverage: Data spans functional annotations from more than 20 species.
• Consolidated validated annotations: Experimentally validated function annotations for dual-function RNAs (cncRNAs, bifunctional RNAs) are centralized for analysis.
• Support for method development: The curated dataset is suitable for analysis and for training or benchmarking RNA function prediction methodologies.

Scientific Applications:

• Functional annotation: Cataloging and annotating protein-coding and noncoding roles of individual RNAs, including translated ncRNAs and untranslated mRNAs.
• Mechanistic studies: Investigating molecular roles and mechanisms of dual-function RNAs in cellular processes.
• Comparative analyses: Comparing conservation and functional patterns of cncRNAs across multiple species.
• Predictive model development: Training and benchmarking computational predictors for RNA coding/noncoding status and multifunctionality.

Methodology:

Entries were compiled and validated through manual curation of experimentally supported RNA functions.
