SimPhospho

SimPhospho simulates phosphopeptide tandem mass spectra to generate spectral libraries that improve confidence in phosphosite assignment in mass spectrometry-based phosphoproteomics.

Key Features:

• Phosphopeptide spectrum simulation: Simulates tandem mass spectra of phosphopeptides with reported high sensitivity and precision.
• Spectral library generation: Produces simulated phosphopeptide spectral libraries for use in validation workflows.
• Database search augmentation: Uses simulated spectra to validate and augment database search results for phosphoproteome identification.
• Phosphosite confirmation: Enables confirmation of site-specific phosphorylation events on peptides.
• Pipeline integration: Supports integration with the Trans-Proteomic Pipeline for incorporation into proteomics workflows.

Scientific Applications:

• Phosphosite assignment validation: Improves accuracy and confidence in assigning phosphorylation sites from mass spectrometry data.
• Spectral library-based identification: Augments database search results by providing reference spectra for phosphorylated peptides.
• Study of phosphorylation dynamics: Facilitates confirmation of site-specific phosphorylation events relevant to cellular signaling pathways.

Methodology:

Simulates phosphopeptide tandem mass spectra and generates simulated phosphopeptide spectral libraries, which are used to validate and augment database search results and integrate with the Trans-Proteomic Pipeline.
