title: Tumor suppressor activities of the Fbw7 E3 ubiquitin ligase receptor.
abstract: The F-box protein Fbw7/Sel-10/hCdc4/Ago, which is known to regulate ubiquitination and degradation of numerous important regulators of cell division and death including Notch, cyclin E, c-Jun and c-Myc, has been recently rediscovered as a p53-dependent tumor suppressor. Delineation of the mechanisms of Fbw7 anti-oncogenic activities and of its inactivation in human cancers is expected to gain an important insight into tumorigenesis.
