• Protein tyrosine phosphatase web site of Nick Tonks's lab at Cold Harbor Spring Laboratory provides a peer-reviewed compendium on Protein Tyrosine Phosphatases (PTPs) that integrates sequence and structure information with cellular and biological function a resource for annotation and classification of the classical, tyrosine-specific PTPs.
  • HuPho Web Site is an on-line web resource developed by the Molecular Genetics Group at the Department of Biology of the University of Rome Tor Vergata, to assist scientists in the task of recovering information about human phosphatases.
  • PTP central is a comprehensive resource on eukaryotic protein tyrosine phosphatases (PTPs).
  • DEPOD - the human DEPhOsphorylation Database the human DEPhOsphorylation Database (version 1.1) is a manually curated database collecting human active phosphatases, their experimentally verified protein and non-protein substrates and dephosphorylation site information, and pathways in which they are involved.
