I have used Network-Analyzer Cytoscape plugin to identify hub proteins - nodes with the highest node degree distribution - in my protein-protein interaction networks.
Now I would like to identify nodes interacting with my hub proteins. I want to perform an enrichment analysis (with cytoscape plugin BiNGO) to identify biological processes enriched in relation with my hub proteins.
How can I extract subnetwork cluster consisting of proteins interacting with my hub proteins? I can't seem to work around that task with the NetworkAnalyzer plugin. I would also appreciate if someone could suggest to me other or better alternatives.
