We report the introduction of functional RNA molecules into yeast spheroplasts. Plasmids containing the firefly luciferase coding region were transcribed to yield RNAs suitable for introduction into yeast cells and direct assay of their translation products. The 5' noncoding regions of the RNAs were derived either from the 5' noncoding regions of firefly luciferase, poliovirus, or yeast virus-l...
G-protein-coupled receptors (GPCRs) regulate a wide variety of physiological processes and are important pharmaceutical targets for drug discovery. Here, we describe a unique concept based on yeast cell-surface display technology to selectively track eligible peptides with agonistic activity for human GPCRs (Cell Wall Trapping of Autocrine Peptides (CWTrAP) strategy). In our strategy, individua...
ABSTRACT First Person is a series of interviews with the first authors selection papers published in Disease Models & Mechanisms, helping researchers promote themselves alongside their papers. Koray Ütkür author on ‘ DPH1 and DPH2 variants that confer susceptibility to diphthamide deficiency syndrome human cells yeast models’, DMM. PhD student lab Prof. Dr Raffael Schaffrath at Universität ...
Melanin has been implicated in the pathogenesis of several important human fungal pathogens. Existing data suggest that the conidia of the dimorphic fungal pathogen Sporothrix schenckii produce melanin or melanin-like compounds; in this study we aimed to confirm this suggestion and to demonstrate in vitro and in vivo production of melanin by yeast cells. S. schenckii grown on Mycosel agar produ...
Phytohemagglutinin (PHA), the major seed lectin of the common bean, Phaseolus vulgaris, accumulates in the parenchyma cells of the cotyledons. It has been previously shown that PHA is cotranslationally inserted into the endoplasmic reticulum with cleavage of the NH2-terminal signal peptide. Two N-linked oligosaccharide side chains are added, one of which is modified to a complex type in the Gol...
Wee1-related kinases function in a highly conserved mechanism that controls the timing of entry into mitosis. Loss of Wee1 function causes fission yeast and budding yeast cells to enter mitosis before sufficient growth has occurred, leading to formation of daughter cells that are smaller than normal. Early work in fission yeast suggested that Wee1 is part of a cell-size checkpoint that prevents...
The capacity of Acanthamoeba to distinguish nutritive yeast particles from non-nutritive plastic beads during phagocytosis was investigated. When cells were allowed to phagocytose yeast to capacity, endocytosis stopped and subsequent presentation of particles (either yeast or beads) did not result in further uptake. By contrast, when cells were allowed to phagocytose plastic beads to capacity a...
Yeast cells undergo programed cell death (PCD) with characteristic markers associated with apoptosis in mammalian cells including chromatin breakage, nuclear fragmentation, reactive oxygen species generation, and metacaspase activation. Though significant research has focused on mitochondrial involvement in this phenomenon, more recent work with both Saccharomyces cerevisiae and Schizosaccharom...
conclusions our results demonstrated no significant correlation between the ird5 lifespan and the trehalose concentration. likewise, the correlation between lifespan extension, trehalose accumulation, and cellular resistance to hydrogen peroxide was not significant. results the lifespan of the ird5 mutant was significantly longer that of either the ird11 mutant or the wild type cells. under rep...
Mammalian Ran-binding protein-1 (RanBP1) and its fission yeast homologue, sbp1p, are cytosolic proteins that interact with the GTP-charged form of Ran GTPase through a conserved Ran-binding domain (RBD). In vitro, this interaction can accelerate the Ran GTPase-activating protein-mediated hydrolysis of GTP on Ran and the turnover of nuclear import and export complexes. To analyze RanBP1 function...
