Identification of novel SCF FBXW7 substrates in asynchronous and mitotic cells


ABSTRACT: FBXW7 loss-of-function has been implicated in chemoresistance against antimicrotubule drugs. FBXW7 is frequently mutated in human cancers and the identification of FBXW7 substrates, which could be involved in this phenotype, is a major task.

During prolonged mitotic arrest induced by antimicrotubule drugs, cell fate decision is determined by two alternative pathways, one leading to cell death and the other inducing premature escape from mitosis by mitotic slippage. FBWX7, a member of the F-box family of proteins and substrate-targeting subunit of the SKP1-CUL1-F-Box E3 ubiquitin ligase complex, promotes mitotic cell death and prevents mitotic slippage, but molecular details underlying these roles for FBWX7 are unclear. In this study  ...[more]
