Function |
Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Recognizes and binds phosphorylated sites/phosphodegrons within target proteins and thereafter bring them to the SCF complex for ubiquitination. Identified substrates include cyclin-E (CCNE1 or CCNE2), DISC1, JUN, MYC, NOTCH1 released notch intracellular domain (NICD), NFE2L1, NOTCH2, MCL1, and probably PSEN1. Acts as a negative regulator of JNK signaling by binding to phosphorylated JUN and promoting its ubiquitination and subsequent degradation. Involved in bone homeostasis and negative regulation of osteoclast differentiation. Regulates the amplitude of the cyclic expression of hepatic core clock genes and genes involved in lipid and glucose metabolism via ubiquitination and proteasomal degradation of their transcriptional repressor NR1D1; CDK1-dependent phosphorylation of NR1D1 is necessary for SCF(FBXW7)-mediated ubiquitination. Also able to promote 'Lys-63'-linked ubiquitination in response to DNA damage. The SCF(FBXW7) complex facilitates double-strand break repair following phosphorylation by ATM: phosphorylation promotes localization to sites of double-strand breaks and 'Lys-63'-linked ubiquitination of phosphorylated XRCC4, enhancing DNA non-homologous end joining.

Experiment for Molecule Alteration |

Experiment for Drug Resistance |
MTS assay | |||
Mechanism Description | FBW7, an E3 ubiquitin ligase and a tumor suppressor frequently mutated in CRCs, contribute to resistance to targeted therapies. CRC cells containing FBW7 inactivating mutations are insensitive to clinically used multi-kinase inhibitors of RAS/RAF/MEK/ERK signaling, including regorafenib and sorafenib. In contrast, sensitivity to these agents is not affected by oncogenic mutations in KRAS, BRAF, PIK3CA, or p53. These cells are defective in apoptosis due to blocked degradation of Mcl-1, a pro-survival Bcl-2 family protein. Deleting FBW7 in FBW7-wild-type CRC cells abolishes Mcl-1 degradation and recapitulates the in vitro and in vivo drug resistance phenotypes of FBW7-mutant cells. CRC cells selected for regorafenib resistance have progressive enrichment of pre-existing FBW7 hotspot mutations, and are cross-resistant to other targeted drugs that induce Mcl-1 degradation. Furthermore, a selective Mcl-1 inhibitor restores regorafenib sensitivity in CRC cells with intrinsic or acquired resistance. |
