Interallelic interaction and gene regulation in budding yeast.
InDrosophila, homologous chromosome pairing leads to "transvection," in which the enhancer of a gene can regulate the allelic transcription intrans.Interallelic interactions were also observed in vegetative diploid budding yeast, but their functional significance is unknown. Here, we show that aGAL1reporter can interact with its homologous allele and affect its expression. By ectopically insert...
متن کاملRegulation of histone gene expression in budding yeast.
We discuss the regulation of the histone genes of the budding yeast Saccharomyces cerevisiae. These include genes encoding the major core histones (H3, H4, H2A, and H2B), histone H1 (HHO1), H2AZ (HTZ1), and centromeric H3 (CSE4). Histone production is regulated during the cell cycle because the cell must replicate both its DNA during S phase and its chromatin. Consequently, the histone genes ar...
متن کاملTranscriptional regulation of meiosis in budding yeast.
Initiation of meiosis in Saccharomyces cerevisiae is regulated by mating type and nutritional conditions that restrict meiosis to diploid cells grown under starvation conditions. Specifically, meiosis occurs in MATa/MATalpha cells shifted to nitrogen depletion media in the absence of glucose and the presence of a nonfermentable carbon source. These conditions lead to the expression and activati...
متن کاملInteraction Networks of Prion, Prionogenic and Prion-Like Proteins in Budding Yeast, and Their Role in Gene Regulation
Prions are transmissible, propagating alternative states of proteins. Prions in budding yeast propagate heritable phenotypes and can function in large-scale gene regulation, or in some cases occur as diseases of yeast. Other 'prionogenic' proteins are likely prions that have been determined experimentally to form amyloid in vivo, and to have prion-like domains that are able to propagate heritab...
متن کاملElectrochemical Regulation of Budding Yeast Polarity
Cells are naturally surrounded by organized electrical signals in the form of local ion fluxes, membrane potential, and electric fields (EFs) at their surface. Although the contribution of electrochemical elements to cell polarity and migration is beginning to be appreciated, underlying mechanisms are not known. Here we show that an exogenous EF can orient cell polarization in budding yeast (Sa...
