F-box and WD repeat domain-containing 7 regulates intestinal cell lineage commitment and is a haploinsufficient tumor suppressor

Abstract

The E3 ubiquitin ligase F-box and WD repeat domain-containing 7 (Fbw7) degrades several proto-oncogenes including c-Myc, cyclinE, Notch1, and c-Jun. Fbw7 is the fourth most frequently mutated gene in human colorectal carcinomas and has recently been described as a poor prognosis marker in human colorectal carcinoma; however, the molecular mechanism underlying fbw7 mutations in intestinal tumor suppression is unclear.
