Alignment-free protein interaction network comparison
MOTIVATION Biological network comparison software largely relies on the concept of alignment where close matches between the nodes of two or more networks are sought. These node matches are based on sequence similarity and/or interaction patterns. However, because of the incomplete and error-prone datasets currently available, such methods have had limited success. Moreover, the results of netw...
متن کاملProtein-Protein Interaction Network Alignment
Proteins are some of the building blocks of organisms. They usually perform their functions by interacting with each other and forming protein complexes. A protein-protein interaction network is a graph that consists of proteins as vertices and their interactions as edges. Protein-protein interaction network alignment is very important in identifying protein complexes and predicting protein fun...
متن کاملSPINAL: scalable protein interaction network alignment
MOTIVATION Given protein-protein interaction (PPI) networks of a pair of species, a pairwise global alignment corresponds to a one-to-one mapping between their proteins. Based on the presupposition that such a mapping provides pairs of functionally orthologous proteins accurately, the results of the alignment may then be used in comparative systems biology problems such as function prediction/v...
متن کاملProper evaluation of alignment-free network comparison methods
MOTIVATION Network comparison is a computationally intractable problem with important applications in systems biology and other domains. A key challenge is to properly quantify similarity between wiring patterns of two networks in an alignment-free fashion. Also, alignment-based methods exist that aim to identify an actual node mapping between networks and as such serve a different purpose. Var...
