ABSTRACT
The invasive and filamentous growth forms of Saccharomyces cerevisiae are adaptations to specific environmental conditions, under particular conditions of limited nutrient availability. Both growth forms are dependent on the expression of the FLO11 gene, which encodes a cell-wall-associated glycoprotein involved in cellular adhesion. A complex regulatory network consisting of signaling pathways and transcription factors has been associated with the regulation of FLO11. Mss11p ...

Cumulative Mutations Affecting Sterol Biosynthesis in the Yeast Saccharomyces cerevisiae Result in Synthetic Lethality That Is Suppressed by Alterations in Sphingolipid Profiles
Genetics
; ABSTRACT UPC2 and ECM22 belong to a Zn(2)-Cys(6) family of fungal transcription factors and have been implicated in the regulation of sterol synthesis in Saccharomyces cerevisiae and Candida albicans. Previous reports suggest that double deletion of these genes in S. cerevisiae is lethal depending

The Histone Deubiquitinating Enzyme Ubp10 Is Involved in rDNA Locus Control in Saccharomyces cerevisiae by Affecting Sir2p Association
Genetics
; ABSTRACT Histone modifications influence chromatin structure and thus regulate the accessibility of DNA to replication, recombination, repair, and transcription. We show here that the histone deubiquitinating enzyme Ubp10 contributes to the formation/maintenance of silenced chromatin at the rDNA by

A Role for Sterol Levels in Oxygen Sensing in Saccharomyces cerevisiae
Genetics
; ABSTRACT Upc2p and Ecm22p are a pair of transcription factors responsible for the basal and induced expression of genes encoding enzymes of ergosterol biosynthesis in yeast (ERG genes). Upc2p plays a second role as a regulator of hypoxically expressed genes. Both sterols and heme depend upon

Evidence That Spt10 and Spt21 of Saccharomyces cerevisiae Play Distinct Roles in Vivo and Functionally Interact With MCB-Binding Factor, SCB-Binding Factor and Snf1
Genetics
; ABSTRACT Mutations in SPT10 and SPT21 of Saccharomyces cerevisiae have been previously shown to cause two prominent mutant phenotypes: (1) defects in transcription of particular histone genes and (2) suppression of Ty and δ-insertion mutations (Spt^sup -^ phenotype). The requirement for Spt10

Multiple regulatory mechanisms maintain zinc homeostasis in saccharomyces cerevisiae
The Journal of Nutrition
; ABSTRACT Zinc is an essential nutrient, yet it is toxic if it accumulates in excess amounts within cells; therefore the intracellular labile zinc content of cells is tightly controlled. In Saccharomyces cerevisiae, zinc homeostasis is regulated by the controlled activity of zinc uptake transporters
