About OmniPath

OmniPath is a database of molecular biology prior knowledge, combining data from over 100 resources to build 5 integrated databases:

  • Signaling network (interactions)
  • Enzyme-PTM relationships
  • Protein complexes
  • Protein annotations (function, localization, tissue, disease, structure)
  • Intercellular communication roles (ligand, receptor, intercell)
