Abstract

Significance p73 is expressed as multiple C-terminal isoforms, but their expression and activity are largely unknown. Here, we identified p73α1 as a p73 C-terminal isoform that results from exon 12 (E12) exclusion. We showed that E12 deficiency in mice leads to systemic inflammation but not spontaneous tumors. We also showed that Notch1 is regulated by p73α1 and plays a critical role in p73-dependent tumor suppression and systemic inflammation.
