Promoter-dependent roles for the Srb10 cyclin-dependent kinase and the Hda1 deacetylase in Tup1-mediated repression in Saccharomyces cerevisiae.
The Tup1-Ssn6 complex has been well characterized as a Saccharomyces cerevisiae general transcriptional repressor with functionally conserved homologues in metazoans. These homologues are essential for cell differentiation and many other developmental processes. The mechanism of repression of all of these proteins remains poorly understood. Srb10 (a cyclin-dependent kinase associated with the M...

متن کاملNFATc2-mediated repression of cyclin-dependent kinase 4 expression.
The calcineurin-regulated transcription factor, nuclear factor of activated T cells (NFAT), controls many aspects of T cell function. Here, we demonstrate that the calcineurin/NFAT pathway negatively regulates the expression of cyclin-dependent kinase 4 (CDK4). A canonical NFAT binding site was identified and found to be sensitive to calcium signals, FK506/CsA, and histone deacetylase activity ...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولNegative regulation of Gcn4 and Msn2 transcription factors by Srb10 cyclin-dependent kinase.
The budding yeast transcriptional activator Gcn4 is rapidly degraded in an SCF(Cdc4)-dependent manner in vivo. Upon fractionation of yeast extracts to identify factors that mediate Gcn4 ubiquitination, we found that Srb10 phosphorylates Gcn4 and thereby marks it for recognition by SCF(Cdc4) ubiquitin ligase. Srb10 is a physiological regulator of Gcn4 stability because both phosphorylation and t...
