INO hierarchy and selected INO key terms. INO is aligned with BFO. It imports most PSI-MI interaction type terms to represent the various interaction types. Some bottom level interaction terms (e.g., phosphorylation) are replaced with corresponding GO terms. Many INO-specific terms (e.g., regulation) that do not exist in PSI_MI or GO are also generated. Note that there are different interactors but only input interactor is shown here. The network and pathway related terms are not shown.
