Graphlets and motifs in biological networks
Weba null model (Fig. 1), unlike network motifs. Also, unlike network motifs, graphlets must be induced subgraphs, whereas motifs are partial subgraphs, which makes graphlets more precise measures of network topology compared to motifs [8]. Graphlets have been well established when studying static networks. For example, they were used as a basis ... WebJun 15, 2015 · Our new notion of dynamic graphlets is different from existing dynamic network approaches that are based on temporal motifs (statistically significant subgraphs). The latter have limitations: their results depend on the choice of a null network model that is required to evaluate the significance of a subgraph, and choosing a good null model is ...

Furthermore, we show a way to combine the 73 graphlet degree distributions ...

For technical reasons, comparing large networks is computationally infeasible, and thus heuristics, such as the degree distribution, clustering coefficient, …
Graphlet degree vectors (signatures) and signature similarities were applied to biological networks to identify groups (or clusters) of topologically similar nodes in a network and predict biological properties of yet uncharacterized nodes based on known biological properties of characterized nodes. See more Graphlets in mathematics are induced subgraph isomorphism classes in a graph, i.e. two graphlet occurrences are isomorphic, whereas two graphlets are non-isomorphic.

WebJun 20, 2024 · Network motifs defined as small graphlets that occur more frequently than expected by chance have revolutionized our understanding of feed-back circuits in cellular networks. However, with their definition solely based on statistical over-representation, network motifs often lack biological context, which limits their usefulness.
