Sample pathways represented by P ATIKA ontology. (left) Canonical wnt pathway containing examples of compound structures, such as regular abstractions (e.g., "protein degradation"), homology abstractions (e.g., 5 wnt genes), and molecular complexes (e.g., APC:Axin) [4]. (right) Partial human interaction networks containing PPIs and the transcriptional regulation interactions of proteins CRK and SP1, respectively.
