    Fission Yeast srm1 is Involved in Stress Response and Cell Cycle
    (2017) Gevrekci, Aslihan Ors; 28345120
    Polyamines are well-conserved, multifunctional polycations that contribute to a number of processes in the cells such as cell cycle, apoptosis, stress response, and gene expression. Therefore, polyamine levels should be kept under strict regulation by specific polyamine transporters and polyamine synthases. In this study, the aim is to experimentally characterize a predicted spermidine synthase gene srm1, which was identified upon sequence similarity, in fission yeast Schizosaccharomyces pombe. In an attempt to understand the role of this gene in cell cycle and stress response, deletion mutant of srm1 was generated and analyzed in terms of cell cycle regulation and environmental stress response. The results showed that srm1 Delta cells had elongated cell size and were sensitive to osmotic stress, while they showed no sensitivity to DNA-damaging agents. To the best of our knowledge, this is the first experimental characterization of srm1 gene and its role in cell cycle progression and stress response.
