Autor: Gabriela Forster, Olca Titiz, Thérésa Bridget Fitzpatrick, Marina Tambasco-Studart, Nikolaus Amrhein, Thomas Raschle

Publikováno v: Proceedings of the National Academy of Sciences, Vol. 102, No 38 (2005) pp. 13687-92

Vitamin B6 is an essential metabolite in all organisms. It can act as a coenzyme for numerous metabolic enzymes and has recently been shown to be a potent antioxidant. Plants and microorganisms have a de novo biosynthetic pathway for vitamin B6, but

Sac1 Lipid Phosphatase and Stt4 Phosphatidylinositol 4-Kinase Regulate a Pool of Phosphatidylinositol 4-Phosphate That Functions in the Control of the Actin Cytoskeleton and Vacuole Morphology

Autor: Anjon Audhya, Scott D. Emr, Michelangelo Foti

Publikováno v: Molecular Biology of the Cell, Vol. 12, No 8 (2001) pp. 2396-2411

Synthesis and turnover of phosphoinositides are tightly regulated processes mediated by a set of recently identified kinases and phosphatases. We analyzed the primary role of the phosphoinositide phosphatase Sac1p in Saccharomyces cerevisiae with the

A GAL4-HP1 fusion protein targeted near heterochromatin promotes gene silencing

Autor: Daniel Pauli, Pierre Spierer, Marion Delattre, Anne Spierer, Carole Seum

Publikováno v: Chromosoma, Vol. 109, No 7 (2000) pp. 453-9

We have constructed a new reporter transgene, Winkelried, equipped with a synthetic binding site for the yeast GAL4 transcriptional activator. The binding site is inserted between the white and lacZ reporter genes, and is flanked by FRT sequences. Th

The essential function of not1 lies within the Ccr4-not complex

Autor: Chi Tu, Young-Kwon Hong, Martine A. Collart, Laurent Jean Marie Maillet, Elisabeth O Shuster

Publikováno v: Journal of Molecular Biology, Vol. 303, No 2 (2000) pp. 131-43

The five Saccharomyces cerevisiae Not proteins are associated with the Ccr4 and Caf1 proteins in 1.2 MDa and 2 MDa complexes. The Not proteins have been proposed to repress transcription of promoters that do not contain a canonical TATA sequence, whi

Isolation and characterization of human orthologs of yeast CCR4-NOT complex subunits

Autor: Reiner Gentz, Thomas K. Albert, Nynke L. van Berkum, Marc Lemaire, H. Th. Marc Timmers, Martine A. Collart

Publikováno v: Nucleic Acids Research, Vol. 28, No 3 (2000) pp. 809-17

The yeast CCR4-NOT protein complex is a global regulator of RNA polymerase II transcription. It is comprised of yeast NOT1 to NOT5, yeast CCR4 and additional proteins like yeast CAF1. Here we report the isolation of cDNAs encoding human NOT2, NOT3, N

GintPDX1 encodes a protein involved in vitamin B6 biosynthesis that is up-regulated by oxidative stress in the arbuscular mycorrhizal fungus Glomus intraradices

Autor: Karim Benabdellah, Nuria Ferrol, Concepción Azcón-Aguilar, Thérésa Bridget Fitzpatrick, Davide Speziga, Ascensión Valderas

Publikováno v: New Phytologist, Vol. 184, No 3 (2009) pp. 682-693

Vitamin B6 is an essential metabolite that has recently been implicated in defense against cellular oxidative stress. In fungi, the de novo biosynthetic pathway of vitamin B6 involves two genes, PDX1 and PDX2. Here, we report a component of the PDX1/

The evolution of the eukaryotic endomembrane system and the transport pathways of their vesicular intermediates are poorly understood. A common set of organelles and pathways seems to be present in all free-living eukaryotes, but different branches o
