Welcome!

RokaiXplorer is an interactive tool designed for exploratory data analysis of proteomics and phospho-proteomics data to uncover novel biomarkers and potential clinical targets.

With RokaiXplorer, you can:

  • Identify significant changes in phosphorylation and protein expression with ease,
  • Perform enrichment analysis of gene ontology (GO) terms to gain insights,
  • Infer kinase activities using the RoKAI algorithm.
