Subgraphs composed of four nodes. a. Subgraph that represents a connection pattern associated to MADS domain protein heterotetramers. Each node binds two other nodes in this subgraph. b. Subgraphs that include all those interactions in a. Curved edges with both ends on the same node represent interactions between identical copies of a protein. c. Subgraphs that do not include all the interactions in a.
