Welcome to FusionDB !


A gene fusion event can be an indicator for a fuctional link or structural interaction between two proteins.

Enter a gene name or a COG id and click on the button.

Gene- fusion events are not the only resource to determine functional links between two proteins. Similar phylogenetic profiles and conserved chromosomal co-localisation can also be used as an indicator for such interactions.
