Summary: The viral post-translational modification database (virPTM) is designed to serve as a repository of literature-based viral modification sites and predicted modification sites using the scan-x algorithm. At present the database contains only phosphorylation data. Expansion of the database to include additional modifications is expected in the future. Data contributions and feedback are always welcome (contact Daniel Schwartz daniel.schwartz(at)

Control data sets: Positive and negative control data sets used in the determination of the sensitivity and specificity of the scan-x predictor may be obtained here.
