Cho HJ, et al. (2007) Schizosaccharomyces pombe nup97, which Genetically Interacts with mex67, is Essential for Growth and Involved in mRNA Export. J Microbiol 45(4):344-9
Abstract: We have isolated previously three synthetic lethal mutants in Schizosaccharomyces pombe, which genetically interact with mex67, in order to identify the genes involved in mRNA export. A novel nup97 gene was isolated by complementation of the growth defect in one of the synthetic lethal mutants, SLMex3. The nup97 gene contains one intron and encodes an 851 amino-acid protein that is similar to nucleoporins, Npp106p in S. pombe and Nic96p in Saccharomyces cerevisiae. The nup97 gene is essential for vegetative growth, and nup97 null mutant harboring pREP41X-Nup97 showed poly(A)+ RNA export defect when expression of nup97 is repressed in the presence of thiamine. These results suggest that nup97 is involved in mRNA export from the nucleus to cytoplasm.
