What is dbSNO 3.0 ?

dbSNO 3.0 is an integrated knowledgebase for experimentally verified cysteine-centered post-translational modifications, enabling data-driven exploration of regulatory mechanisms, structural determinants, and functional consequences.

Integrated framework of dbSNO 3.0

Integrated framework of dbSNO 3.0 for cysteine PTM annotation, regulatory networks, structural analysis, and functional prediction.

Comprehensive cysteine PTM compendium

60,000+ experimentally verified cysteine modification events curated from literature and public databases.

Regulatory network integration

Protein–protein interaction and pathway networks revealing cysteine-centered functional modules.

Structural characterization

Structural mapping of modification sites to capture spatial and physicochemical context.

LLM-based functional prediction

Sequence-based prediction and functional inference of cysteine PTMs using large language models.

Research highlights

Representative experimental and computational studies that advanced our understanding of cysteine-centered post-translational modifications, spanning S-nitrosylation, S-glutathionylation, and other redox-regulated cysteine modifications, and provided the conceptual and methodological foundations for dbSNO.
