Effects of reciprocal chromosomal translocations on the fitness of Saccharomyces cerevisiae.
Yeast species have undergone extensive genome reorganization in their evolutionary history, including variations in chromosome number and large chromosomal rearrangements, such as translocations. To determine directly the contribution of chromosomal translocations to the whole organism's fitness, we devised a strategy to construct in Saccharomyces cerevisiae collinear "evolutionary mimics" of o...
متن کاملDifferent aneuploidies arise from the same bridge-induced chromosomal translocation event in Saccharomyces cerevisiae.
Chromosome translocations are gross chromosomal rearrangements that have often been associated with cancer development in mammalian cells. The feasibility of drastically reshaping the genome with a single translocation event also gives this molecular event a powerful capacity to drive evolution. Despite these implications and their role in genome instability, very little is known about the mole...
متن کاملSites of ubiquitin attachment in Saccharomyces cerevisiae.
Sites of ubiquitin modification have been identified by mass spectrometry based on the increase in molecular mass of a tryptic peptide carrying two additional glycine residues from the ubiquitin moiety. However, such peptides with GG shifts have been difficult to discover. We identify 870 unique sites of ubiquitin attachment on 438 different proteins of the yeast Saccharomyces cerevisiae.
متن کاملSelection and analysis of spontaneous reciprocal mitotic cross-overs in Saccharomyces cerevisiae.
We developed a system that allows the selection of the reciprocal products resulting from spontaneous mitotic cross-overs in the yeast Saccharomyces cerevisiae. A number of other types of genetic events, including chromosome loss, can be monitored with this system. For a 120-kb chromosome interval on chromosome V (CEN5-CAN1), the rate of mitotic cross-overs was 4x10(-5) per division, a rate app...
متن کاملReciprocal translocations in Saccharomyces cerevisiae formed by nonhomologous end joining.
Reciprocal translocations are common in cancer cells, but their creation is poorly understood. We have developed an assay system in Saccharomyces cerevisiae to study reciprocal translocation formation in the absence of homology. We induce two specific double-strand breaks (DSBs) simultaneously on separate chromosomes with HO endonuclease and analyze the subsequent chromosomal rearrangements amo...
