Phosphorylation-dependent degradation of c-Myc is mediated by the F-box protein Fbw7.
The F-box protein Skp2 mediates c-Myc ubiquitylation by binding to the MB2 domain. However, the turnover of c-Myc is largely dependent on phosphorylation of threonine-58 and serine-62 in MB1, residues that are often mutated in cancer. We now show that the F-box protein Fbw7 interacts with and thereby destabilizes c-Myc in a manner dependent on phosphorylation of MB1. Whereas wild-type Fbw7 prom...
متن کاملDegrasyn activates proteasomal-dependent degradation of c-Myc.
c-Myc is a highly unstable transcription factor whose deregulation and increased expression are associated with cancer. Degrasyn, a small synthetic molecule, induces rapid degradation of c-Myc protein in MM-1 multiple myeloma and other tumor cell lines. Destruction of c-Myc by degrasyn requires the presence of a region of c-Myc between amino acid residues 316 and 378 that has not previously bee...
متن کاملPolyamines regulate c-Myc translation through Chk2-dependent HuR phosphorylation.
All mammalian cells depend on polyamines for normal growth and proliferation, but the exact roles of polyamines at the molecular level remain largely unknown. The RNA-binding protein HuR modulates the stability and translation of many target mRNAs. Here, we show that in rat intestinal epithelial cells (IECs), polyamines enhanced HuR association with the 3'-untranslated region of the c-Myc mRNA ...
متن کاملInvestigation of hPin1 mediated phosphorylation dependency in degradation control of c-Myc oncoprotein
Sammanfattning Cancer is the main cause of death in economically developed countries and the second leading cause of death in developing countries. Along with today’s knowledge that more than two hundred different diseases lie in the category of this prognosis there is an urge for more detailed and case-specific treatments to replace the dramatic actions of available radiationand chemotherapy, ...
متن کاملIn silico identification of transcriptional regulators associated with c-Myc.
The development of powerful experimental strategies for functional genomics and accompanying computational tools has brought major advances in the delineation of transcriptional networks in organisms ranging from yeast to human. Regulation of transcription of eukaryotic genes is to a large extent combinatorial. Here, we used an in silico approach to identify transcription factors (TFs) that for...
