Organization of Physical Interactomes as Uncovered by Network Schemas
Figure 4
Emergent Y-star schemas uncovered in the S. cerevisiae interactome, represented as triangles in a graph where each vertex corresponds to a triplet schema.
Triplet schemas that are themselves emergent (Figure 3) are displayed as darker vertices. (A) An illustration of the triplet subgraph representation of a Y-star schema. The Y-star (on the left) is mapped to three vertices corresponding to its lower-order triplet schemas, along with edges among them; that is, it is represented as a triangle in the graph whose vertices represent triplet schemas. The triplet subschemas of the Y-star are highlighted. The subschemas that are emergent triplets are highlighted in purple and represented as darker vertices. For ease of visualization, the central node of the Y-star is labeled in pink inside the triangle and connected to the vertices by dashed lines. (B) Pfam emergent Y-star schemas. See also Table S5.
