Welcome to I2D!

To faciliate experimentation and integrated computational analysis with model organism PPI networks, we have integrated known, experimental and predicted PPIs for five model organisms and human in the I2D database.

I2D is developed and maintained by Jurisica Lab at Ontario Cancer Institute, PMH. I2D will continue to expand as new protein-protein interaction data becomes available.

NEWS

Significantly expanded physical protein interaction database is now available as IID - Integrated Interactions Database. It is 74% larger than I2D and includes annotation of tissue-specific interactions across 30 tissues.

Visualization

NAViGaTOR is a powerful graphing application for the 2D and 3D visualization of biological networks

When I2D is queried, it can output data in several formats one of which is a NAViGaTOR compatible file. This file can be opened up in NAViGaTOR for visualization and further analysis. I2D can also be queried from within NAViGaTOR.
