UbiBrowser 2.0 is a comprehensive resource for proteome-wide known and predicted ubiquitin ligase (E3)/deubiquitinase (DUB) - substrate interactions in eukaryotic species. These E3/DUB-substrate interactions are derived from five data sources: manual curation, protein GO annotation, protein domain, protein motif and network topology.

A computational framework developed by us (Nature Communications, 2017, 8) was used to combine multiple biological evidences to generate a confidence score for the derived proteome-wide ubiquitin ligase (E3)/deubiquitinase (DUB)-substrate interactions in 39 eukaryotic species.More..

Notice: Due to the update of our prediction system, there is some difference between the predicted human ESIs results in UbiBrowser 2.0 and those in UbiBrowser 1.0. To make our prediction results reproducible, we provide the link to our previous UbiBrowser 1.0 website. You can use the human ESI prediction results from either UbiBrowser 1.0 or 2.0, because all of them were supported by certain biological evidences. Sorry for the possible confusion.

UbiBrowser 2.0 was developed at Beijing proteome research center (BPRC).

Browser compatibility: we support the latest versions of the Chrome, Firefox, Opera, Safari and Internet Explorer (version 10 and 11).

Chrome is the recommended browser.
