Relationships between InterPro entries
InterPro entries often share relationships with other entries in the database. For example, an entry might represent a functionally-specific subfamily of a larger family, or a subclass of a broad class of domains. These relationships are stored in InterPro as hierarchies, which are displayed as trees in the relationship section of an entry page (Figure 8).
Both family and domain entries are able to form hierarchical relationships, although family and domain hierarchies are kept separate in the database and do not overlap (for example, a subclass of a particular domain can not be a subtype of a protein family). Repeats and sites are not arranged into hierarchical relationships.
