Regulation of Cidea protein stability by the ubiquitin-mediated proteasomal degradation pathway.
Cidea, one of three members of the CIDE (cell-death-inducing DNA-fragmentation-factor-45-like effector) family of proteins, is highly enriched in brown adipose tissue, in which it plays a critical role in adaptive thermogenesis and fat accumulation. Cidea-null mice have increased energy expenditure with resistance to high-fat-diet-induced obesity and diabetes. However, little is known as to how...
متن کاملRegulating the Yeast Kinetochore by Ubiquitin-Dependent Degradation and Skp1p-Mediated Phosphorylation
In S. cerevisiae, the four-protein Cbf3 complex binds to the essential CDEIII region of centromeric DNA to initiate kinetochore assembly. We report the reconstitution of Cbf3p from recombinant proteins and an analysis of its p58Ctf13 and p23Skp1 subunits. p23Skp1 has both G1- and G2-specific functions in yeast and binds to p58Ctf13 and to the essential Cdc4p component of the ubiquitin conjugati...
متن کاملTUSC4 functions as a tumor suppressor by regulating BRCA1 stability.
BRCA1 expression is lost frequently in breast cancers in which it promotes malignant development. In the present study, we performed a global expression analysis of breast cancer cells in which the tumor-suppressor candidate gene TUSC4 was silenced to gain insights into its function. TUSC4 silencing affected genes involved in cell cycle and cell death, which have broad reaching influence on can...
متن کاملBRCA1 loss activates cathepsin L–mediated degradation of 53BP1 in breast cancer cells
Loss of 53BP1 rescues BRCA1 deficiency and is associated with BRCA1-deficient and triple-negative breast cancers (TNBC) and with resistance to genotoxic drugs. The mechanisms responsible for decreased 53BP1 transcript and protein levels in tumors remain unknown. Here, we demonstrate that BRCA1 loss activates cathepsin L (CTSL)-mediated degradation of 53BP1. Activation of this pathway rescued ho...
متن کاملEnhanced Protein Degradation by Branched Ubiquitin Chains
Posttranslational modification of cell-cycle regulators with ubiquitin chains is essential for eukaryotic cell division. Such chains can be connected through seven lysine residues or the amino terminus of ubiquitin, thereby allowing the assembly of eight homogenous and multiple mixed or branched conjugates. Although functions of homogenous chain types have been described, physiological roles of...
