Navigation
Below is displayed the entity view of the selected entity. Entity view is shown in the form of scheme expressing relations part of (green), contains (orange), substrate of rule (red) and product of rule (blue). The navigation panel on the left shows the entity in corresponding model and allows you to browse the biological structure of the model. Manipulation with the navigation panel is realized by unfolding the items in the navigation tree and clicking on a requested system level.

Annotations Tab
All the annotation links to relevant databases for the currently selected entity are displayed on the Annotation Tab below the scheme.

Models Tab
The Models Tab displays all models containing selected entity.
