UbiBrowser is a resource of known and predicted human ubiquitin ligase (E3) - substrate interaction network.

The E3-substrate interactions are derived from six data sources: mannual cruration, protein ortholog, protein domain, protein motif and network topology.

A computational framework is used to to combine multiple biological evidences to generate a confidence score using Naïve Bayesian Network. 397,496 predicted and mannually crurated human E3-substrate can be explored in the current version. More..

UbiBrowser has been 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.
