Involvement of N-terminally truncated variants of p73, deltaTAp73, in head and neck squamous cell cancer: a comparison with p53 mutations.

Abstract excerpt

p73, a p53-related gene, encodes two classes of isoforms with opposing functions: (1) a full-length transactivation-competent p73 protein (TAp73) with tumour suppressor activity; and (2) a group of NH2-terminally truncated, transactivation-deficient p73 proteins, deltaEx2p73, deltaEx2-3p73, deltaNp73 and deltaN'p73 (collectively named deltaTAp73) with oncogenic activity. In this study, for the first time, we...
