MoonDB v2.0 (January 2018 datafreeze):

MoonDB v2.0 contains an updated list Extreme Multifunctional (EMF) protein candidates from the MoonGO pipeline, as well as manually curated extreme multifunctional or moonlighting proteins.

The detection of EMF proteins is dependent on knowledge of protein-protein interactions and GO term annotations, therefore the list of candidates varies with the increase of functional knowledge for each species.

MoonDB will be updated every year with a new list of EMF proteins.
