%X In this study, we used a combination of structure based virtual screening and an in vitro deubiquitinase (DUB) assay to identify several small molecules that inhibit TRABID DUB activity. However, these inhibitors failed to show inhibitory effects on ¦Â-catenin-mediated gene transcription. In addition, expression of TRABID shRNAs, wildtype TRABID, or the DUB activity-deficient mutant showed little effects on ¦Â-catenin-mediated gene transcription.TRABID may not be a critical component in canonical Wnt/¦Â-catenin signal transduction or that a minute amount of this protein is sufficient for its role in regulating Wnt activity.
