Cell cycle-dependent regulation of the Skp2 promoter by GA-binding protein.
Skp2 is the F-box protein component of an SCF-type ubiquitin ligase that interacts specifically with p27(Kip1) and thereby promotes its ubiquitylation and degradation. The abundance of Skp2 mRNA oscillates in a cell cycle-dependent manner, being maximal in S and G(2) phases. The regulation of Skp2 transcription was investigated by cloning the promoter region of the mouse gene and determination ...
متن کاملAcetylation-Dependent Regulation of Skp2 Function
Aberrant Skp2 signaling has been implicated as a driving event in tumorigenesis. Although the underlying molecular mechanisms remain elusive, cytoplasmic Skp2 correlates with more aggressive forms of breast and prostate cancers. Here, we report that Skp2 is acetylated by p300 at K68 and K71, which is a process that can be antagonized by the SIRT3 deacetylase. Inactivation of SIRT3 leads to elev...
متن کاملMicrotubule-dependent cell cycle regulation
Interstitial cells of Hydra attenuata, from which nerve cells and nematocytes (stinging cells) differentiate, were arrested in either metaphase or G2 by different concentrations of the microtubule-depolymerizing agent nocodazole. At a concentration of 1*4 nM-nocodazole, a large number of cells were arrested in metaphase. However, at concentrations of 2 nM-nocodazole and above most of the cells ...
متن کاملCrashing waves of destruction: the cell cycle and APC(Cdh1) regulation of SCF(Skp2).
Coordination of events required for cell cycle progression is orchestrated in large part by the ubiquitin (Ub)-mediated destruction of key regulatory proteins such as cyclins and their inhibitors. Until now, the G1/S and mitotic phases of the cell cycle were thought to be controlled by discrete families of multisubunit Ub-ligases: SCF ligases controlled the G1 to S transition, whereas APC ligas...
متن کاملRole of the F-Box Protein Skp2 in Adhesion-Dependent Cell Cycle Progression
Cell adhesion to the extracellular matrix (ECM) is a requirement for proliferation that is typically lost in malignant cells. In the absence of adhesion, nontransformed cells arrest in G1 with increased levels of the cyclin-dependent kinase inhibitor p27. We have reported previously that the degradation of p27 requires its phosphorylation on Thr-187 and is mediated by Skp2, an F-box protein tha...
