Abstract

Background: The biological function of the ASB family of ubiquitin ligases is poorly characterized. Results: A family-wide analysis of ASB-associated proteins by mass spectrometry identified novel interactors. Conclusion: ASB proteins can associate in multimeric complexes. Asb11 ubiquitinates Ribophorin 1 and regulates its turnover. Significance: This data resource will facilitate the characterization of the biological function of ASB proteins.
