Identification of a GTPase-activating protein homolog in Schizosaccharomyces pombe.
Loss of function of the Schizosaccharomyces pombe gap1 gene results in the same phenotypes as those caused by an activated ras1 mutation, i.e., hypersensitivity to the mating factor and inability to perform efficient mating. Sequence analysis of gap1 indicates that it encodes a homolog of the mammalian Ras GTPase-activating protein (GAP). The predicted gap1 gene product has 766 amino acids with...
متن کاملHeteroduplex DNA formation and homolog pairing in yeast meiotic mutants.
Previous studies of Saccharomyces cerevisiae have identified several meiosis-specific genes whose products are required for wild-type levels of meiotic recombination and for normal synaptonemal complex (SC) formation. Several of these mutants were examined in a physical assay designed to detect heteroduplex DNA (hDNA) intermediates in meiotic recombination. hDNA was not detected in the rec102, ...
متن کاملCharacterization of Schizosaccharomyces pombe Rad2 protein, a FEN-1 homolog.
FEN-1 proteins are a family of nucleases essential for lagging strand DNA synthesis. A gene with sequence similarity to FEN-1 protein-encoding genes, rad2 +, has been identified in Schizosaccharomyces pombe . We report the overexpression, purification, and character-ization of the putative S.pombe FEN-1 homolog, Rad2p. A GST-Rad2p fusion protein was over-expressed in Saccharomyces cerevisiae an...
متن کاملS. pombe placed on the prion map
Schizosaccharomyces pombe has been used extensively as a model organism, however it is only recently that the first prion in this organism, a copper transporter protein encoded by ctr4, has been conclusively demonstrated. Prions are found in a wide range of organisms and have been implicated in a number of human neurodegenerative diseases. Research into the biology of prions has been carried ou...
متن کاملS. pombe genome deletion project: an update.
The fission yeast Schizosaccharomyces pombe is a model organism used widely to study various aspects of eukaryotic biology. A collection of heterozygous diploid strains containing individual deletions in nearly all S. pombe genes has been created using a PCR based strategy. However, deletion of some genes has not been possible using this methodology. Here we use an efficient knockout strategy b...
