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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
