**Now released for Cytoscape 3!**
The CyTargetLinker app extends biological networks with regulatory interactions, for example miRNA-target, TF-target or drug-target interactions. Network nodes need to have an attribute containing a biological identifier, eg. Ensembl or NCBI Gene, to link to regulatory information.
Regulatory data gets extracted from so called *Regulatory Interaction Networks* **(RegINs)**. You can download these network files from the CyTargetLinker website or create your own.
Check out our tutorials on the website to learn how to use CyTargetLinker.
