Graphlets and motifs in biological networks

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. WebOct 3, 2016 · Introduction.

WebJan 28, 2024 · Typed graphlets are a powerful generalization of the notion of graphlet (network motif) to heterogeneous networks as they capture both the induced subgraph of interest and the types associated with the nodes in the induced subgraph. To address this problem, we propose a fast, parallel, and space-efficient framework for counting typed … WebDec 9, 2013 · Network graphlets and motifs are statistically highly recurrent patterns in graphs and networks that have been found to characterize families of networks and … how did chucky have a kid https://pammiescakes.com

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.
