Sterol Regulatory Element Binding Proteins in Fungi: Hypoxic Transcription Factors Linked to PathogenesisAmerican Society for Microbiology -  Tập 9 Số 3  - Trang 352-359 - 2010
Clara M. Bien, Peter J. Espenshade
ABSTRACT
          
            Sterol regulatory element binding proteins (SREBPs) are membrane-bound transcription factors whose proteolytic activation is controlled by the cellular sterol concentration. Mammalian SREBPs are activated in cholesterol-depleted cells and serve to regulate cellular lipid homeostasis. Recent work demonstrates that SREBP is functionall......  hiện toàn bộ
 Independent Metalloregulation of Ace1 and Mac1 in Saccharomyces cerevisiaeAmerican Society for Microbiology -  Tập 4 Số 11  - Trang 1863-1871 - 2005
G A Keller, Amanda Bird, Dennis R. Winge
ABSTRACT
          Ace1 and Mac1 undergo reciprocal copper metalloregulation in yeast cells. Mac1 is functional as a transcriptional activator in copper-deficient cells, whereas Ace1 is a transcriptional activator in copper-replete cells. Cells undergoing a transition from copper-deficient to copper-sufficient conditions through a switch in the growth medium show a......  hiện toàn bộ
 Role of Heat Shock Transcription Factor in Saccharomyces cerevisiae Oxidative Stress ResponseAmerican Society for Microbiology -  Tập 6 Số 8  - Trang 1373-1379 - 2007
Ayako Yamamoto, Junko Ueda, Noritaka Yamamoto, Naoya Hashikawa, Hiroshi Sakurai
ABSTRACT
          
            The heat shock transcription factor Hsf1 of the yeast
            Saccharomyces cerevisiae
            regulates the transcription of a set of genes that contain heat shock elements (HSEs) in their promoters and function in diverse cellular processes, including protein folding. Here, we show that Hsf1 activ......  hiện toàn bộ
 Regulation of Thermotolerance by Stress-Induced Transcription Factors in Saccharomyces cerevisiaeAmerican Society for Microbiology -  Tập 7 Số 5  - Trang 783-790 - 2008
Noritaka Yamamoto, Yuka Maeda, Aya Ikeda, Hiroshi Sakurai
ABSTRACT
          
            The heat shock transcription factor Hsf1 and the general stress transcription factors Msn2 and Msn4 (Msn2/4) are major regulators of the heat shock response in
            Saccharomyces cerevisiae
            . Here, we show that transcriptional activation of their target genes, including

 Copper-Dependent Iron Assimilation Pathway in the Model Photosynthetic EukaryoteChlamydomonas reinhardtiiAmerican Society for Microbiology -  Tập 1 Số 5  - Trang 736-757 - 2002
Sharon La Fontaine, Jeanette Quinn, Stacie S. Nakamoto, M. Dudley Page, Vera Göhre, Jeffrey L. Moseley, Janette Kropat, Sabeeha Merchant
ABSTRACTThe unicellular green algaChlamydomonas reinhardtiiis a valuable model for studying metal metabolism in a photosynthetic background. A search of theChlamydomonasexpressed sequence tag database led to the identification of several components that form a copper-dependent iron assimilation pathway related t......  hiện toàn bộ
