Defining mechanisms of cellular stress responses driven by heterotypic ubiquitin chains
Posttranslational modification of proteins with monoubiquitin or different polyubiquitin chains alter protein function to signal distinct responses in cells and thereby regulate every aspect of eukaryotic biology. Recently, ubiquitin has also been reported to form branched heterotypic chains. The central premise of this proposal is that branched ubiquitin chains adopt unique conformations and convey distinct intracellular signals essential for maintaining cellular homeostasis. We posit that branching of homotypic ubiquitin chains or de novo formation of branched structures occurs in response to specific cues and they serve as priority signals to mediate prompt cellular responses.
