The NPS1/STH1 gene encodes a nuclear protein essential for the progression of G2/M phase in Saccharomyces cerevisiae . Nps1p shares homology to Snf2/Swi2p, a subunit of a protein complex known as the SNF/SWI complex. Recently, Nps1p was found to be a component of a protein complex termed RSC (3) essential for mitotic growth, whereas its function is unknown.(More)
Signalling via calcium is probably involved in regulating eukaryotic cell proliferation, but details of its mechanism of action are unknown. In Schizosaccharomyces pombe, the onset of mitosis is determined by activation of a complex of the p34cdc2 protein kinase and a cyclin protein that is specific to the G2 phase of the cell cycle. This activation(More)
Although transcriptional factors are known to play important roles in synaptic plasticity, their role in olfactory adaptation has not been studied well. Here we report that Ce-TBX-2, the TBX2/TBX3 transcriptional factor homologue of the nematode Caenorhabditis elegans, is involved in olfactory adaptation. Two missense hypomorphic mutations in this gene(More)
The IME2 gene is one of the key regulators of the initiation of meiosis in budding yeast. This gene is repressed during mitosis through the repressive chromatin structure at the promoter, which is maintained by the Rpd3-Sin3 histone deacetylase (HDAC) complex. IME2 expression in meiosis requires Gcn5/histone acetyltransferase, the transcriptional activator(More)
The nucleotide sequences of RNA segment 7 (nonstructural protein gene; NS) were compared among 34 influenza C virus strains isolated between 1947 and 1992. The results showed that all the NS genes analysed had the potential to encode NS1 and NS2 proteins of 246 and 182 amino acids, respectively. The deduced amino acid sequence of the previously unidentified(More)
The uncapping of telomeres induces a DNA damage response. In Schizosaccharomyces pombe, deletion of pot1+ causes telomere uncapping and rapid telomere resection, resulting in chromosome fusion. Using the nmt-pot1-aid strain, we previously reported that Pot1 shut-off causes telomere loss and chromosome fusion in S. pombe. However, the factors responsible for(More)
RSC (Remodel the Structure of Chromatin) is an ATP-dependent chromatin remodeling complex essential for the growth of Saccharomyces cerevisiae. RSC exists as two distinct isoforms that share core subunits including the ATPase subunit Nps1/Sth1 but contain either Rsc1or Rsc2. Using the synthetic genetic array (SGA) of the non-essential null mutation method,(More)
