Gene Ontology (GO)
GO depicts three complementary biological concepts including Biological Process (BP), Molecular Function (MF) and Cellular Component (CC). The hierarchical structure of GO is organized as a directed acyclic graph (DAG) by viewing an individual term as a node and its relations to parental terms (allowing for multiple parents) as directed edges. To navigate this hierarchy, we display all parental GO terms to the current GO term of interest ordered by their shortest distances to the current term. Also, only direct children GO terms of the current GO term are listed.
Structural Classification of Proteins (SCOP)
SCOP classifies evolutionary-related domains into Superfamily level and Family level. Accordingly, we have generated the domain-centric GO annotations for each of the three concepts at each of the two domain levels.
Structural Domain Functional Ontology (SDFO)
As domain-centric ontology, SDFO only refers to those GO terms which are the most informative to annotate SCOP domains.
Supra-domain Functional Ontology (SPFO)
As an extension, SPFO includes those GO terms which are the most informative to annotate supra-domains and individual SCOP domains at the Superfamily level.
