From: Integration of the Gene Ontology into an object-oriented architecture
The GO terms associated with the process, TGF-beta receptor complex assembly (GO: GO:0007181). Lines with solid diamonds (
) at the end indicate composition. These are read from the diamond end, for example, as 'cell' (GO:0005623) contains a 'membrane' (GO:0016020). Lines with open triangles (
) represent generalizations. These are read from the triangle end, as a 'membrane' (GO:0016020) is a general type of 'plasma membrane' (GO:0005886). A) Directed acyclic graph for the cellular component GO terms associated with TGF-beta receptor complex assembly (GO:0007181). B) Object-oriented representation of the DAG described in Figure 1A (white). Additional cellular components not represented by the current Gene Ontology, but essential to the TGF-beta receptor complex assembly process are shown in the gray boxes (i.e. TGF-beta, TGF-beta receptors, SMAD2)
