Protein Neighbourhood Information (PNI) can be obtained for any gene of interest from the human genome. The NeuroDNet database PNI was collected from various databases like HPRD, BioGrid, MINT, DIP and Reactome. The interactions between the gene of interest and its interacting partners are shown graphically where neighbours are positioned radially. The user has the option of expanding the neighbourhood information up to the third degree of interactions. After generating the neighbourhood information, the user may also save the output as a text file which can be visualized in any graphical software such as Cytoscape.
