  • Prions are infectious proteins, in which self-propagating amyloid conforma-tions of proteins are transmitted. The budding yeast Saccharomyces cerevi-siae, one of the best-studied model eukaryotes, also has prions, and thus provides a tractable model system with which to understand the mechanisms of prion phenomena.

  • Ubiquinone is an essential factor for the electron transfer system and is also a known lipid antioxidant. The length of the ubiquinone isoprenoid side-chain differs amongst living organisms, with six isoprene units in the budding yeastSaccharomyces cerevisiae, eight units in Escherichia coliand 10 units in the fission yeast Schizosaccharomyces pombeand in humans.

  • The functional expression of olfactory receptors (ORs) is a primary require-ment to examine the molecular mechanisms of odorant perception and cod-ing. Functional expression of the rat I7 OR and its trafficking to the plasma membrane was achieved under optimized experimental conditions in the budding yeast Saccharomyces cerevisiae. The membrane expression of the receptor was shown by Western blotting and immunolocalization meth-ods.

  • Mitochondrial ribosomal proteins (mrps) of the budding yeast, Saccharomyces cerevisiae, have been extensively characterized genetically and biochemically. However, the list of thegenes encoding individualmrps is still not complete and quite a fewof the mrps are only predicted from their similarity to bacterial ribosomal proteins. We have con-structed a yeast strain in which one of the small subunit proteins, termed Mrp4, was tagged with S-peptide and used for affinity purification of mitochondrial ribosome. ...

  • DNA replication, the process of copying one double stranded DNA molecule to produce two identical copies, is at the heart of cell proliferation. This book highlights new insights into the replication process in eukaryotes, from the assembly of pre-replication complex and features of DNA replication origins, through polymerization mechanisms, to propagation of epigenetic states. It also covers cell cycle control of replication initiation and includes the latest on mechanisms of replication in prokaryotes. The association between genome replication and transcription is also addressed.

  • It has been widely accepted that most coenzyme Q (CoQ) exists freely in the mitochondrial membrane as a CoQ pool. However, the recent identifi-cation of a mitochondrial CoQ-binding protein, termed Coq10, in budding yeast has the potential to change our current view of CoQ status in mem-branes.

  • Mitotic chromosome structure depends on the chromosomal condensin complex. Without condensin, metaphase chromosomes remain undercondensed and lack structural stability. We have asked where along budding yeast chromosomes the condensin complex associates, and what we can learn from its binding pattern about the mechanism of chromosome condensation.

  • Septins are a family of conserved proteins that are essential for cytokinesis in a wide range of organisms including fungi, Drosophila and mammals. In budding yeast, where they were first discovered, they are thought to form a filamentous ring at the bridge between the mother and bud cells.

  • The centromere–kinetochore complex is a highly specialized chromatin domain that both mediates and monitors chromosome–spindle interactions responsible for accurate partitioning of sister chromatids to daughter cells. Centromeres are distinguished from adjacent chromatin by specific patterns of histone modification and the presence of a centromere-specific histone H3 variant (e.g. CENP-A). Centromere-proximal regions usually correspond to sites of avid and persistent sister chromatid cohesion mediated by the conserved cohesin complex.

  • DNA replication is restricted to a specific time window of the cell cycle, called S phase. Successful progression through S phase requires replication to be properly regulated to ensure that the entire genome is duplicated exactly once, without errors, in a timely fashion. As a result, DNA replication has evolved into a tightly regulated process involving the coordinated action of numerous factors that function in all phases of the cell cycle. Biochemical mechanisms driving the eukaryotic cell division cycle have been the subject of a number of mathematical models.

  • In eukaryotes, two heteroheptameric Sm-like (Lsm) complexes that differ by a single subunit localize to different cellular compartments and have dis-tinct functions in RNA metabolism. The cytoplasmic Lsm1–7p complex promotes mRNA decapping and localizes to processing bodies, whereas the Lsm2–8p complex takes part in a variety of nuclear RNA processing events.

  • In budding yeast, the protein phosphatase Cdc14 is a key regulator of late mitotic events. Research over the last decade has revealed many of its func-tions and today we know that this protein phosphatase orchestrates several aspects of chromosome segregation and is the key trigger of exit from mitosis.

  • The budding yeastSaccharomyces cerevisiaepossesses a very flexible and complex programme of gene expression when exposed to a plethora of environmental insults. Therefore, yeast cell homeostasis control is achieved through a highly coordinated mechanism of transcription regulation invol-ving several factors, each performing specific functions. Here, we present our current knowledge of the function of the yeast activator protein family, formed by eight basic-leucine zipper trans-activators, which have been shown to play an important role in stress response....
